apollo 12 saturn v

The launch of Gemini XII with Jim Lovell and Buzz Aldrin.  I never knew a photo existed showing the transition of the two programs.  Most likely, the Saturn V in the background was the 500F, which was a full size mock-up for mating testing or testing launchpad mechanisms before launches with live rockets would begin.  Still, a very good photo documenting the transition from the Gemini to the Apollo program.
