I'm a big fan of the National Parks of America, and I will always visit one or more on my trips. Between 1935 and 1943 a special government project let American artists, all over the country make the above shown posters. They where used by the local Chamber of Commerce as a marketing tool to get visitors to the parks etc. They were not for sale. Due to their fragile nature only a few original posters have survived to this day. These rare images were rescued and restored by Ranger Doug.
