I found these really cool photographs of Mercury Project astronauts Gus & Virgil Grissom with suit technician Joe Schmidt on Apollo Mission Photos. The Mercury Missions were the United States first attempt at putting a man into orbit around the earth. The program ran from 1959-1963. The Mercury-Atlas 6 mission was the first flight to achieve the goal. The astronaut suits along with the undergarments are unbelievable. It must have been a real thrill to have the challenge of designing something with such advanced function and technology.
