This vibrant silkscreen poster was produced in a small run to promote a dinosaur attraction at Disneyland that was part of the train ride surrounding the park. The poster was not made for sale but only for use as a display within the park. The ride was decommissioned in the Seventies and a few remaining posters were sold to visitors.
It is not surprising to see Disney on the cutting edge of this vibrant "Pop" period of American graphic design. The other worldliness of the dinosaurs is strongly evoked by acid green and yellow contrasted by purple and neon blue.
