ANONYMOUS JENNY LAKE MUSEUM. Circa 1938. 19x14 1/8 inches. Condition A-: pencil in image; pinholes in corners; discoloration in margins. Silk-screen. Printed on thick stock. Signed into being in 1929, western Wyoming's Grand Teton National Park originally consisted of the Teton Range of mountains, and 6 glacial lakes located at the base of the mountains. No museum at Jenny Lake exists currently (a visitor center can be found there now). In the early 1930s the Federal Government was trying to get citizens out to the National Parks to experience the breathtaking scenery and the entire natural experience. The Ranger Naturalists on hand at this and other National parks were intended to help visitors feel more comfortable on their trips. The posters, trying to make the experience as irresistible as possible, made sure to promote these "eco-tour guides" as a "free government service." The park was enlarged during the 1940s by land purchased by John D. Rockefeller, with the intent of preserving the wild, natural beauty of the area. It appears that this poster was the earliest of this series of National Parks posters, as the typography is different from all of the others.
