Andrene Kauffman was an artist and art educator who spent most of her life in the Chicago area. Like too many of the post office muralists I’ve featured, most online examples of her work are found on auction sites. There are a few prints at the website for the Art Institute of Chicago and one at the website for the National Gallery.
Kauffman painted one post office mural: Preparations for the First County Fair in Ida Grove – 1872 (Ida Grove, Iowa).
