Little can be found online about Fred A. Mayer. The only biographical information I found is that he was born in 1904. There are a few books available that he illustrated. Other than that, he's almost unknown.
This article, from the 1940 Ringling Bros and Barnum and Bailey Circus Magazine and Daily Reviewprovides a little bit about the artist.
