A hand silk-screened poster for Disneyland's Frontierland. Featuring a vibrant depiction of Disneyland's Mark Twain riverboat, Indian War Canoes, and defunct Keel boats, the attraction poster advertises "Exciting Adventures" on the Rivers of America. The very early park poster was designed by Bjorn Aronson and intended to be reminiscent of the popular travel posters of the 1950's, exemplifying the bold colors and simple, yet powerful compositions of that time. Due to the laborious process of silk-screen printing, the park printed multiples of this poster when it was designed, and as the park displayed poster would fade and wear, a replacement would be pulled from the printed inventory. The early silk-screened posters are some of the most identifiable and vivid representations of the early park. Measuring 54"x36", the attraction poster is in very good condition with small indications of wrinkles and light edge wear that is barely visible due to linen backing preservation.
