The Grand Canyon National Park poster was produced for the Ranger Naturalist Service, a department of the National Park Service. The poster was created in 1938 as part of the Works Project Administration, or WPA. This poster has been faithfully reproduced by a team of artists. Using an original poster, every detail was reproduced to create the highest quality poster available. The original design used pinks and purples for an artistic view but we have carefully replaced these colors with a more realistic and pleasing look. Heavy stock paper was used to produce a non-reflective matte finish for a look and feel of the original silk screened posters. Please check our other items for a high quality frame for this poster.
