Although the Ralph A. Sawyer collection includes materials relating to all phases of his career, beginning with his studies at the University of Chicago in 1918-1919, the strength of the files are for those activities outside of the University of Michigan, notably his work with the U.S. Navy laboratories, Joint Task Force One, the American Institute of Physics, and the Optical Society of America. Files dealing with his University of Michigan activities are less complete as these materials will be found with the records of those units which Sawyer headed.

The Roberta Keniston Postcard Collection contains six boxes of postcards and other visual ephemera from the 20th century. The collection focuses mostly in European architecture and painting. The majority of the postcards are blank, but some do include correspondence.

The Roberta Keniston Postcard Collection contains six boxes of postcards and other visual ephemera from the 20th century. The boxes are first organized by donor, and then very broadly divided by the type of architecture or artwork depicted on the postcards. These subdivisions are arranged by geographic region, media, and/or subject of the work shown on the postcard.

The majority of items in this collection are postcards dating from 1900-1918, which was during the “golden age” of postcard collecting, lasting from about 1895 to 1915. Other items, including photographs, souvenir photo books, greeting cards, and exhibition announcements in this collection were published throughout the 20th century. Correspondence to and from History of Art faculty and staff appear on some of the postcards.
