A Project Mercury MA-6 commemorative cover that has been hand signed by Astronaut John Glenn. The cover displays the cancellation stamp dated with the launch date of the mission. Mercury-Atlas 6 (MA-6), also known as "Friendship 7", was the first crewed American orbital spaceflight, launched on February 20, 1962, with astronaut John Glenn making three orbits around Earth, successfully returning the same day. The mission, a key part of NASA's Project Mercury, marked a significant milestone by placing a human in Earth orbit and observing their reaction to space. The cover is in excellent condition with minimal handling wear.
