Background:
The WPA Posters stamps are being issued as Forever stamps in 10 designs, in a pressure-sensitive adhesive booklet of 20 stamps. Forever stamps are always equal in value to the current First-Class Mail 1-ounce price.

Antonio Alcalá served as the art director of the project and designed the stamps with Maribel O. Gray.

The booklet features designs originally created to support the civic-minded ideals of former president Franklin D. Roosevelt’s New Deal Program.

Formed in 1935 as the Works Progress Administration, renamed the Work Projects Administration in 1939, the WPA lasted until 1943. By then, the function of its Federal Art Program Poster Division had been fully absorbed into the World War II effort.

During the Depression, the project employed 5,000 artists nationwide, who designed and printed some two million posters from approximately 35,000 designs. At the project’s height, cities in 18 states had Poster Project offices.

Most of their work was printed by silkscreen, an economical medium that saw significant innovation at the hands of Poster Division artists. The posters featured on these stamps are from the Prints & Photographs Division of the Library of Congress, which houses the largest collection of WPA posters.
