This collection has been minimally processed and is organized into several general series. These include correspondence, breeding and production records, financial records, incubation and banding reports, advertisements and other promotional literature, honors and awards, poultry industry trade magazines, and photographs and artwork. Almost all of the materials document the Hanson Leghorn Farm, a nationally significant poultry breeding business located in Corvallis, Oregon.
Photographs include views of various aspects of the Hanson Farm operation -- pens, brooder houses, other outbuildings, and prize chickens; homes on the Hanson estate; deliveries of chicks to the Corvallis train station for delivery around the world. Also included are portraits of Jesse A. Hanson, images of other family members, and views of hunting and fishing activities. Prints have been made of most of the nitrate film negatives.
