This 1963 5¢ Flag over White House First Day Cover features the Scott 1208 stamp canceled on February 24 at the Arizona Pioneers' Historical Society Exhibition Station in Tucson, Arizona.
The stamp was issued to meet the new 5-cent first-class letter rate that took effect in 1963, showing the American flag waving above the White House to symbolize national pride during the Cold War era.
The distinctive circular exhibition station postmark from the Arizona Pioneers' Historical Society adds philatelic interest beyond a standard Washington, DC first-day cancel.
The cover is addressed to Mrs. S. A. Mattern in Spring Hill, Massachusetts, a quiet residential area north of Boston with deep colonial roots.
A solid mid-century U.S. FDC for collectors of flag topical issues or Arizona postal history, in clean condition with a clear, well-struck postmark.
