Here's a collection of my favorite National Park Posters! These are all original works created, numbered, signed and dated. The posters are created in the style of the Works Progress Administration (WPA), when — in the 1930s and 1940s — the Federal Government commissioned hundreds of artists to create thousands of poster designs for public exhibits, community activities, theatrical productions, health, safety and educational programs, nature and travel. By the end of the WPA era, only 26 National Parks had been established and only 14 parks had posters created for them. Photographer and graphic artist, Robert B. Decker, studied photography with Ansel Adams in the summer of 1979 in Yosemite National Park when he was just 19…an experience that solidified his love of photography and our National Parks. Now he is on a journey to photograph and create iconic WPA-style posters of all our major national parks as we celebrate the next 100 years of the National Park Service.
