The Adolph Shulz Collection was originally acquired by the Indianapolis Museum of Art in 1971, at the time that the IMA acquired a series of Shulz artwork with the accession numbers 71.217.1-23. This collection contains black and white photographs of the Shulz family in the original photo album, including individual studio portraits of different members of the family through the years. There are several black and white landscape photographs of areas near the Shulz family home in Delavan, Wisconsin. Loose photographs portray Adolph frequently outdoors and several depict him sketching and painting. Other materials included are a handwritten description of a painting from September 24, 1917 and contact sheets and negatives of an unidentified scrapbook which contains sketches of multiple Shulz artworks. Three mounted black and white photographs of T.C. Steele paintings were stored inside of the photo album, and have been separated into an OVA folder.

The Papers of Onya La Tour document the personal and professional life and associations of the art collector, dealer, and museum founder from Brown County, Indiana. The archival collection came to the Indianapolis Museum of Art when her personal collection of art was transferred to the museum. The collection has been divided into six series which are described below.
