Project Mercury To The Moon button

Project Mercury was the first human spaceflight program of the U.S. It ran from 1959-1963 with the goal of putting a human in orbit around the Earth.
The Mercury-Atlas 6 flight on February 20 in 1962, was the first American flight to achieve this goal.
The button is pewter and backmarked Chr. It is much brighter than the image shows. I have 1 available under the metal category @ Pegs Buttons sorry its SOLD
