All of the covers below were done, for Argosy, by the artist Robert Graef. Born in New York City, Robert Graef started his career in 1900 and was still active and working at the time of his death in 1951. For those five decades, Graef worked out of the same art studio at 70 Fifth Avenue in New York. As shown below, the work that he created in that studio has lived on:

All of the paperback covers below were done by an illustrator named Harvey Kidder. Born in Massachusetts, he served as an engineer in World War II and was a member of The Society of Illustrators, The Graphic Artists Guild and was a volunteer with the Pocantico Hills Fire Department. He was also the author of “The Kids Book in Chess,” which has been in print since 1970 and is widely considered to be one of the best “beginner” chess manuals ever written.
Check out some of his paperback work below. My favorite is The Double Take.
