Superb vintage pin back button in support of the 1968 "Olympic Project for Human Rights". Button is NRMT and measures 2 1/2" across. It is very clean with bright graphics and little to no oxidation on the back. The "pin back" is separated from the button, but neither piece is damaged. The button can easily be put back together. This style button was worn by many US Olympic athletes during the 1968 games to raise awareness of the Civil Rights Movement.
