Alphonzo Thomas entered SPSM in 1923. While serving a life sentence, Thomas became a nationally known cartoonist and editor for The Spectator, drawing political, religious, and sports figures such as boxer Jack Dempsey and George Washington. Thomas' drawings were prominently featured in New York's Grand Central Galleries' "Prison Art Exhibit."
Pictured above is Thomas' drawing of boxer Jack Dempsey and a cartoon strip that humorously depicts a man's first day in prison.
