It was called "The Penners of Park Avenue" (other references have titled it "The Park Avenue Penners".) Penner was a comedian best known for the catchphrase "Wanna Buy a Duck?" (or "Do you want to buy a duck?") He died in 1941. (Note: his contemporary, Groucho Marx, used a similar line.) Cover art shows Penner, a can of Cocomalt and a musical band of six dwarves. Cover art signed by "Biro" who was Charles Biro. Chesler (actually Harry Chesler, Sr.) was a comic book publisher whose studio created the publication for R.B. Davis. It is called "Book No. 1", but it was only a one-time publication. While copyrighted 1938 and the radio show ran to mid-1938, references for the issue date of the book usually state 1939. A racist depiction of an African holding a sign card titled "Book No. 1" is seen.
