This small collection related to transportation design was donated by John Treacy to Art Center after a nostalgic visit to the campus. It consists of photocopies of two letters and two automobile sketches, and four photographs of car designs by John Treacy and J. Gordon Legg.

This book contains clippings, correspondence, brochures, and photographs related to Jergenson's professional organizations, The Society of Art Center Alumni, an Art Center trip to Europe, and student projects. The section on professional organizations begins with a handwritten brief history of industrial design societies, especially S.I.D. and IDI, and his participation in them over the years. In 1959, he and Strother MacMinn travelled to Norway, Sweden, England, Italy, and France on behalf of the Industrial Design Department and the trip is documented with correspondence and photos. Much of the images of student work are clippings from Art Center catalogs, but also included are photos of Jergenson teaching classes. Of special interest are photographs of students building and testing watercraft for the 1961 Catalina Project.

This scrapbook covers Jergenson's freelance career as well as a trip to Japan for Art Center. Photographs, handwritten notes, and advertisements document the many projects he worked on including appliances, automobiles (American Motor Co.), airplanes (Pan Am), boats (Outboard Marine Co.), and advertising. In 1956, Jergenson travelled to Japan with Tink Adams and John Coleman to advise on the design of export items. They visited over 30 factories in six and a half weeks. Photos of the trip are accompanied by an itinerary, student lists, a Kabuki program, and a brochure for the Suehiro Grill in Tokyo. Also included are photographs of notable designers visiting Art Center.

The seven scrapbooks in this series offer a comprehensive overview of Jergenson's life, especially his careers in industrial design and education. Compiled by Jergenson in the 1980s, they consist mostly of clippings, photographs, and correspondence with some handwritten exposition. Book 1 documents the early years in Jergenson's life, including his school days and beloved fishing trips. Book 2 are examples of advertisements he created while an art director at M. E. Harlan Advertising. Book 3 documents Jergenson's career at General Motors Styling, predominately during his first tenure there, 1936-1947. Book 4 contains publicity, mostly newspaper and magazine clippings, about the Train of Tomorrow and Art Center. Book 5 covers Jergenson's freelance career as well as a trip to Japan for Art Center. Book 6 contains items related to Jergenson's professional organizations, The Society of Art Center Alumni, an Art Center trip to Europe, and student projects. Book 7 is a unique photo album that includes family trees for Jergenson's ancestors and descendants, as well as in-laws.
