A unique and rare little piece of history. A U.S.A.F Commander wrote a letter to his son telling him about the dinner at the embassy and meeting the astronauts. He had them sign the U.S. Embassy napkin in the upper right corner. The signature bears the names of Wally Schirra (Apollo 7) and Frank Borman (Apollo 8) —which the 50th anniversary just passed. Letter is dated 28, Feb 1966. Napkin is in good shape with some staining and fold marks.
