From the NASA archives, this is a lot of (3) 'Space exploration' color photos. The first photo is titled 'Our Solar System' and shows the planets in relative size to each other and their elliptical orbits, with the reverse featuring various facts about our solar system. The second photo has the Space Shuttle Endeavor lifting off into space on mission STS-100, with NASA facts printed on the reverse, and the third photo is of another spectacular Shuttle launch from 'Complex 39A' at the Kennedy Space Center.
