The Nellie M. Gebers papers date from 1991 to 1995 and measure 1 linear inch. The bulk of the collection is an autobiography originally written in longhand by Gebers towards the end of her life and typed and edited by her son Don Gebers. The rest of the collection consists of an essay about old age and living in a nursing home, correspondence with the M. H. de Young Memorial Museum in San Francisco about Grant Wood, and an instructional guide on Gebers' process for the encaustic painting method.
