(United Artists, 1956) Fantastic original color 27 x 41 one sheet movie poster for the United Artists release of the 1956 Weird West horror film The Beast of Hollow Mountain, inspired by a story written by special effects innovator Willis O'Brien and starring Guy Madison and Patricia Medina in what is cinema's first film to show dinosaurs and cowboys in the same picture. The richly colored poster features the large head of a toothy dinosaur with images of cowboys against a red background with bold caption to right side: "From the dim dawn of history…a monster beyond belief!" Lower border bears an NSS caption line and is numbered "56/360." In fine, folded condition, with pin holes to corners and light rippling at the bottom.
