Two distinct versions of the Gemini 6 mission logo artwork were created, reflecting the change in the objective of the mission itself.
The original GTA-6 version (shown in the top images on the right), showed the Gemini 6 spacecraft performing a rendezvous with an Agena target vehicle
but when the Agena launch failed the Gemini 6 mission had to be rethought.
When the mission was finally launched with the modified objective of performing a rendezvous with Gemini 7 a new modified patch
design was used (shown in the lower images on the right) with the Agena replaced by the Gemini 7 spacecraft.
Embroidered versions of both designs were created for the crew but prior to that, for the formal Gemini 6 crew portrait sessions the crew
wore a version of the GTA-6 design that was actually printed (perhaps on leather).
