Button is 2x3-1/8" made in 1969 with address of Detroit maker on curl "Button Man." This button has been autographed, in somewhat abbreviated form, by Country Joe on the front center in black marker. He signed the button at a concert for Vietnam veterans in Detroit in the 1990s. Button has a little line of air under the perimeter as made but button remains Mint as made and the autograph is clear and bold. Also see John Sinclair button #532. Morry Greener Collection.
