This First Day Cover bears the 4¢ Social Security stamp issued by the United States Post Office, cancelled in Washington, DC on September 26, 1964. The cover features the official first-day postmark alongside the stamp design printed directly on the envelope with the bold inscription "FIRST DAY OF ISSUE."
The stamp commemorates the Social Security program, enacted in 1935 as a cornerstone of the New Deal to provide retirement income, disability benefits, and financial security for American workers and families during the Great Depression and beyond.
A notable detail is the stamp's distinctive slogan "For the People - By the People" encircling photographic vignettes of citizens from all walks of life, emphasizing the program's democratic foundation and broad public support.
This clean, well-centered example makes an excellent addition to collections focused on U.S. social history, New Deal legislation, or mid-century definitive stamps.
