The Gemini IV prime (Ed H. White & James McDivitt) and back-up (Frank Borman & James A. Lovell) crews trying to be not too serious. A very interesting photo to me for two reasons, hilarity apart. First, they are wearing the early David Clark G3-C with the then classic silver outer layer. Those spacesuits were only employed during training and never saw operational use. Of note also the skids landing gear of the Gemini capsule model, part of the astonishing Gemini Para-Glider recovery concept.
