This Artmaster cacheted First Day Cover features the 8¢ United States flag stamp issued May 10, 1971, and postmarked in Washington, DC on the first day of issue.
The stamp was released to coincide with the increase in the first-class letter rate to 8 cents, reflecting the Postal Service's transition to self-supporting operations under the Postal Reorganization Act of 1970.
The cachet prominently displays the U.S. Postal Service eagle logo and explicitly notes the 1971 rate increase, making this cover a direct postal-history artifact of that change rather than a generic flag issue.
A fine addition for collectors of rate-change FDCs, Artmaster cachets, or modern U.S. postal history, with clean strike and attractive graphics.
