Susan Delin Davis was born and raised in Bozeman, Montana. She graduated from Montana State University with a B.S. in Art. Her family visited Yellowstone often when she was a young girl and it became her favorite place. Susan worked the summers of 1967 and 1968 in West Yellowstone, Montana. She loved everything Yellowstone and purchased her first collectible in 1967, a boxed set of Haynes postcards. This was the beginning of what would become the world’s largest Yellowstone Park-related private collection, numbering more than 20,000 items. Susan married Jack Davis, and together they worked to expand and upgrade the collection.
Jack Davis studied environmental science at UCSB and UCD in California. They are the authors and publishers of Samuel L. Schmucker: The Discovery of His Lost Art and The Haynes Family in Yellowstone National Park 1881-1968. They have written several articles on collecting Yellowstone postcards and souvenirs.
The Davises opened an antique postcard and paper ephemera shop in Bozeman in 1990. Olde America Antiques was the only shop of its kind between Minneapolis and Spokane. Susan and Jack also organized and hosted six National Park Antique and Paper Shows in Bozeman from 1993 to 1998. This was the only show in the country with a focus on national park antiques and collectibles. Their shop and antique shows were instrumental in increasing the awareness and popularity of Yellowstone postcards in particular, and national park postcards in general. Yellowstone postcards became some of the most widely collected postcards in the hobby, due in large part to the Davises.
Susan and Jack were longtime members of the International Federation of Postcard Dealers and conducted business throughout the world. Their Yellowstone Park postcards, numbering more than 10,000, is the most comprehensive of its kind. The Davis Yellowstone collection contains a wide range of antiques and collectibles other than postcards, such as souvenirs, photographs, stereoviews, books, advertising, artwork and posters. Their collection resides in the Heritage and Research Center in Gardiner, Montana, where it is available to those wishing to learn more about the park’s history.
The Davises are authorities on Yellowstone Park antiques and collectibles and work as consultants with the park. The 2001 fall issue of Yellowstone Science states, “Susan and Jack Davis have devoted their lives to acquiring, organizing, researching, and upgrading the most complete privately held collection of park memorabilia known to exist.”
