The Mary Hammes Corbin collection includes a scrapbook from her time at Michigan State College. Included are photos of Mary and student life including her friends, football games, and push cart races. The scrapbook also incudes event programs, letters and cards from family, as well as materials received from campus administration. Some of these materials were originally in the scrapbook. Of note is a letter about raids on women's residences. The collection also includes football game program programs and tickets, as well as programs for various events, including some off campus. Also included are landscape architecture syllabi, Campus Capsules (MSC Newsletters to parents), student receipts, fees, schedules, and a rule sheet called West Yakeley Standards. The collection also contains photographs of Mary Hammes, her parents[?], her friends, Beal Garden, and a landscape architecture class. There is also a sketch of an unidentified woman, which may be Mary Hammes. The sketch might be one that Mary described in a letter in the correspondence folder.

The collection also includes photographs of her father John Hammes, in group portraits with other students.
