Political cartoons have long been a way for artists and their editors to bring attention to important social issues or political corruption and to support meaningful causes. The NPS History Collection includes drawings by some of the most influential cartoonists from the 1920s to the 1950s. Their support publicized the National Park Service (NPS) while helping build political support to protect park resources from commercial interests.
Many visitors to national parks today collect passport stamps, magnets, or other items to recall their trip and to show others where they’ve been. In the 1920s and 1930s the “must have” souvenirs weren’t created to be collected. National Park Service (NPS) windshield stickers served a practical administrative purpose; they were evidence that the automobile license fee drivers paid at some parks had been paid. Even so, Americans embraced their colorful, artistic designs.
Between 1938 and 1941 the National Park Service (NPS) Western Museum Laboratories (WML) created many iconic posters. Often described as “the WPA park posters,” they should be called “the WML posters.” Research reveals more designs than previously thought (including several previously unknown ones), reevaluates what is known about the artists, and argues that modern reproductions have made the designs more significant to NPS graphic identity today than they were in the past.
How do fish get up the mountain? By horse, of course! When is a plant not a plant? When you plant a fish! What? No, those aren’t nonsensical kids’ jokes. Photographs from the NPS Historic Photograph Collection will help explain.
