3.5” issued for the “Borman-Lovell” flight which featured the joining of 2 space capsules while in orbit. Button illustrates 2 capsules with an arrow design pointing at each with the text above “Six Feet.” The celluloid on this button is extremely thin as made and susceptible to marks. This has such marks as very tiny indents on the upper center in an area about .75” in dia. While these show under most light conditions, the button retains its total gloss and the celluloid has not torn as we’ve seen on several other examples. Still VF and quite scarce. From 1965 although button itself is undated.
