Towering 1,267 feet above the plains of northeastern Wyoming is Devils Tower National Monument. This monolithic rock formation was featured in Steven Spielberg’s 1977 film, “Close Encounters of a Third Kind.” The butte is also sacred to several Native American tribes, and the huge structure was the first U.S. National Monument ever designated. To celebrate the other-worldly appeal of Devils Tower, Anderson Design Group crafted a classic B-movie-like poster. Available as an art print, canvas, metal sign, or postcard, this retro artwork would look great on any wall. To learn more about the butte, check out the National Parks Service.
