These papers were created by one branch of the Hobson family, early settlers in what is now known as Ventura County. Abram Lincoln Hobson (1861 – 1929) owned land throughout southern California and was an owner of Hobson Brothers Packing Company and Hobson City Markets. He was also actively involved in the local community. The documents include both business and personal correspondence and papers relating to his land holdings and business interests.

This collection consists of glass plate negatives, mostly gelatin glass negatives, and some photographic prints. While most of the images in this collection were captured by either John C. Brewster or Waldo Henry Dingman Sr, some may be the work of other photographers. The negatives are largely of Ventura County locations, historic sites, persons, and events, such as parades and holiday celebrations. There are also several boxes of unidentified negatives.
