We leave footprints and take lots of pictures when we visit national parks, but we also spend a good deal of time in park gift shops looking for souvenirs. For some it might be a poster or print, or maybe a coffee cup emblazoned with the park's name.
I've long treasured Yellowstone National Park, and have amassed a nice collection of souvenirs and memorabilia ranging from decorative plates and even salt shakers to stereoviews and hand-painted glass photographs.
Some folks enjoy collecting books that they can page through years later, or even special edition blankets that were made with that specific park in mind.
Understanding that some mementoes you connect to a specific park are found not in the park but at flea markets or antique shops, we'll accept wide-ranging answers for details on what your most-treasured national park souvenirs are. But please let us know what you look for when you're looking for a souvenir.
