This 80sTees.com exclusive GI Joe t-shirt shows a vintage instruction manual for Dreadnoks member Zartan's Chameleon Swamp Skier. The Chameleon Swamp Skier toy was first released in 1984. The Skier could be put together with easy snap-together assembly, and the pivoting front and rear skis could be removed. Sunlight and temperature would change the colors of the skier, making this one of the most popular GI Joe toys of all time!
