As can be seen in photos of the mission, and as with Gemini 3, the Gemini 4 crew did not wear an emroidered mission patch during the flight.
In fact, no embroidered patch was produced for the mission at the time but as the first crew to wear a U.S. flag on the shoulder of their spacesuits
the crew considered this their mission patch.
The commonly-seen Gemini 4 patch
design with a red background and a cartoon-like astronaut in white floating beside the Gemini capsule was never approved by the crew
and bears no resemblance to the insignia of the mission.
However, an insignia did exist for the Gemini 4 mission. This design which incorporated an American Eagle (the intended call sign for the
spacecraft) was used for the Fliteline medallions carried on board.
In 2008 a patch has been produced based on this design with the input and approval of mission commander Jim McDivitt himself
and this patch represents the closest a
patch collector can get to a 'crew patch' for the mission.
These patches are available exclusively from
