Robert McCall's online gallery of a future space travel, from 1960's...

Pictured here - "(48" x 32", oil on board, 1967; collection of National Air and Space Museum). A space plane launches from a half-completed space station, in McCall's classic poster art for the 1968 MGM film 2001: A Space Odyssey. The image is not only a startlingly accurate depiction of the future of space travel, but a powerful symbol of hope, a visual affirmation that humanity has the resources and ingenuity to prosper and thrive in the century to come."
