Rocky Mountain National Park 100th Anniversary Logo
This detailed anniversary logo uses a seal-style design to hold many unique elements related to the park. In the rim sits the name with a keystone shape holding the number 100 at the top. Across the front sits a ribbon holding the word "centennial" and the years of operation. Inside the seal are illustrations of wildlife with flowers and plants below and to the sides of the seal.
