The Ranger of the Lost Art National Park Poster Art Swiss Army Knife Collection by Victorinox features the art of Doug Leen, AKA "Ranger of the Lost Art." Doug is a former Grand Teton National Park ranger with a strong sense of environmental stewardship. In an effort to teach others about the importance of our earth and our National Parks, he created beautiful silk-screen reproductions of the New Deal Era National Park posters. This artwork is now featured on Genuine Swiss Army Knives by Victorinox Swiss Army. Each piece features a national park, with an iconic image on one side, and the name of the park on the opposite side.These pieces make a wonderful memento of park visits, and are a great homage to our Nation's natural treasures.
