The Seamen’s Service Flag and Lapel Button of the American Merchant Marine
Background
When Congress passed the Service Flag Act of 1942 (Public Law 750), authorizing the familiar blue-star banner for families of military personnel, it left unaddressed an entire body of Americans who were dying in even greater proportion at sea – American Merchant Mariners. By mid-1942, the War Shipping Administration (WSA) had organized more than 4,000 vessels and over 200,000 seamen under its control; losses on the North Atlantic and Arctic routes were staggering. Yet the families of these men had no lawful symbol by which to show their service and sacrifice. However, a major shipping company, the United States Lines, acted first, honored the seamen in its employ with a striking banner at its termnal in Manhattan. It was a disgrace that the WSA needed to remedy.

The War Department hesitated to extend the 1942 act to cover civilians under WSA, fearing dilution of the military flag’s authority. The WSA, in turn, asked Congress to legislate a separate emblem that would carry official sanction but a distinct appearance. From this bureaucratic correspondence came one of the least-remembered acts of wartime recognition: the Seamen’s Service Flag and its companion Lapel Button, both authorized in 1943.
Legislation
On 5 April 1943, Representative Schuyler Otis Bland of Virginia—longtime chairman of the House Committee on Merchant Marine and Fisheries—introduced H.R. 2281, “To authorize the issue of suitable insignia and service flags to seamen serving in the American Merchant Marine.” The bill sought to bring parity of symbol, not of rank, acknowledging the mariner’s peril without militarizing his status.
The measure moved swiftly. With little debate in the House and minor amendments in the Senate, it became Public Law 78-52 on 10 May 1943 (57 Stat. 81-82). Its first section provided:
“The War Shipping Administration is authorized to issue suitable insignia and medals to seamen serving in the American Merchant Marine during the war period, and to approve a seamen’s service flag and a seamen’s service lapel button for the immediate family of any such seaman.”
The Senate Commerce Committee added a safeguard clause: any design resembling the Armed Forces’ flag must receive the Secretary of War’s consent. The purpose was not control but coordination to ensure that the new emblem would stand beside, not beneath, the military services in visual dignity.
On 25 September 1943, the details appeared in the Federal Register (Vol. 8, No. 187, p. 13070) as “Service Insignia and Service Flag for the American Merchant Marine.” The order established three related symbols:
- The Merchant Marine Service Emblem (for seamen themselves);
- The Seamen’s Service Flag (for their families); and
- The Seamen’s Service Lapel Button (a miniature personal version of the flag).


The Seamen’s Service Flag
The Seamen’s Service Flag adopted a form both familiar and reversed. Where the Armed Forces’ banner bore a red border enclosing a white field with a blue star, the mariners’ flag was entirely blue with white stars, a symbolic inversion that signified equal honor in a different sphere. Each star represented a member of the immediate family “serving in the American Merchant Marine during the war period.” The flag’s proportions were those of the military design, but its color and absence of red marked it as civilian, peaceful, and oceanic.
The official language specifies:
“The Seamen’s Service Flag shall be of blue bunting, the hoist one and two-thirds times the fly, with one or more white stars corresponding to the number of seamen from the immediate family. In the upper hoist quarter, a white silhouette of a merchant vessel shall appear, and around the border a continuous golden rope terminating in a figure-of-eight knot on the fly.”
Crucially, the same regulation continues:
“If the seaman represented is killed or dies while serving, the white star shall have superimposed thereon a smaller gold star so that the white forms a border.”
The WSA circulated the approved pattern to its training stations and district offices late in 1943. Families could obtain the flag by application through a mariner’s operating company or local WSA office, providing proof of relationship and service. In contrast to the military’s mass-produced blue-star banners, production numbers for the Merchant Marine version were small. Surviving examples are typically silk or rayon, with a gold-stitched merchant-vessel silhouette above one or more white stars appliquéd on navy-blue ground.
Contemporary press releases framed the flag as “a symbol of faithful service in the war’s most perilous field.” Households from Portland to New Orleans hung it beside the better-known military banners, though its blue field was easily mistaken for a state or club pennant. A gold-star variant, signifying death in service, was mentioned in legislation but appears never to have been or produced in numbers.
By the war’s end, fewer than ten thousand flags had been issued. The WSA’s authority expired with demobilization in November 1946, and no agency succeeded it in maintaining the program. As a result, the Seamen’s Service Flag faded from post-war public memory almost as quickly as the ships themselves disappeared from convoy duty.


The Seamen’s Service Lapel Button
Paired with the window flag was a small emblem meant for personal wear—the Seamen’s Service Lapel Button. It fulfilled the same social role for merchant seamen’s families that the blue star pin played for soldiers’ and sailors’ kin. The Federal Register text described it only as “a type to be approved by the War Shipping Administration,” leaving form to the designers.
Design
The approved design featured a gilt-bronze laurel wreath surrounding a rectangular navy-blue enamel tablet, bordered with a rope pattern. In the center of the tablet, a white star rises above the silhouette of a cargo vessel in gold relief. The ship is depicted with its bow and stern in balance, showcasing a single stack and bridgehouse that unmistakably resemble those of the wartime Liberty ship. The symbolism in the design is clear: the star represents service, the ship signifies the fleet that provided the nation’s lifeline, and the wreath symbolizes honor.
The badge measured approximately ⅞ inch by 1 inch, fitted with a simple horizontal safety clasp. Most examples are unmarked, but known manufacturers include Whitehead & Hoag Co. (Newark, NJ) and Green Duck Co. (Chicago, IL), firms already under government contract for military insignia. Each employed vitreous enamel over struck bronze, producing a rich translucent blue that has darkened with age.
Issuance
Eligible recipients were defined as “immediate family members”—parents, spouses, siblings, or children—of any mariner serving under WSA control. Applications were submitted to district WSA offices and verified against ship-assignment rosters. The buttons were presented in small pasteboard boxes printed with “American Merchant Marine in Service,” often accompanied by a leaflet explaining the symbol’s meaning and the obligation “to wear it with pride and prayer.”

In cases of death, the Federal Register again provided explicit authorization:
“When the seaman is killed or dies while serving, the star upon the button shall be gold in color.”

Gold-star lapel buttons were therefore legitimate issue items—contrary to many post-war assumptions that they were unofficial. Surviving specimens confirm the existence of both blue-star and gold-star versions, struck and enameled to identical pattern except for the color of the star.
The button was worn on civilian dress from late 1943 until the cessation of hostilities. By 1947, with the WSA dissolved and mariners returning to peacetime trade, distribution ended. The lapel button quietly disappeared from jewelry counters and remembrance ceremonies alike, its purpose fulfilled yet unrecorded.
Aftermath and Legacy
With the demobilization order of 8 November 1946, the WSA ceased all awards and insignia programs. Production of the Seamen’s Service Flag and Lapel Button ended, and the remaining stock was transferred to the U.S. Maritime Commission for disposal. Unlike the Merchant Marine Service Emblem, which persisted in academy use, the family symbols vanished quietly from public display.
Yet they remain the first—and only—wartime emblems legislated specifically for the families of Merchant Mariners. Both flag and pin gave civilian households a sanctioned form of acknowledgment, binding them to the same language of stars and gold that the nation used for its uniformed dead. Though rare today, these pieces embody the moment Congress recognized that the Merchant Marine was, in every sense but uniform, a service of war.
While the military blue-star banner often takes the spotlight, the Seamen’s Service Flag and Lapel Button symbolize an important moment in recognizing America’s civilian sailors during wartime. They marked the first acknowledgment by Congress that the families of merchant seamen deserved the same right to display a symbol of pride as those of the armed forces. The design of these emblems – deep blue and maritime – reflects the labor of the ocean rather than the glory of the battlefield.
Today, surviving examples are scarce. The fragile silk of the flags has often perished; the enamel on the lapel pins chips easily.
Yet their symbolic lineage endures. Every later effort to grant veterans’ status to Merchant Mariners – from the 1977 Public Law 95-202 to the 1988 Public Law 105-368 – invokes, implicitly, the recognition first codified in 1943. The blue field and white star remain the quiet heraldry of those who served without uniform, whose families waited at windows for ships that never returned.
