Alien 36 inch Puzzle

This interesting looking puzzle was released by HG Toys, presumably in 1979 (there's no copyright on the outside of the box). The artwork is quite nice, and includes, Ripley, Parker, Dallas, Lambert, and Kane in their spacesuits, the Alien, and various other items. The puzzle is a huge 36 inch by 14 1/2 inch beast, and the box itself is around 24 inches by 8 inches. Contains 250 pieces.
