This is one of two stamps issued to commemorate the twenty-fifth anniversary of
the first successful moon landing, on July 20, 1969. This stamp covered the
existing rate for a single ounce of first-class mail and showed a close-up view
of an astronaut holding a U.S. flag on the moon's surface.

The stamp was available from the U.S. Postal Service only in sheetlets of
twelve, in a special commemorative format.

Included on the sheetlet are Neil Armstrong's famous words as he stepped onto
the moon's surface: "That's one small step for man, one giant leap for
mankind."
