Matthew, the artist is Fritz Willis....
He did alot of Pinup art that was used by the Harolds Club. There are several calendars out there along with blotters and other pinup related items. I have a $1 Harolds Club chip if you are interested. $5 shipped. Just let me know. And if you need more info on Fritz please let me know. I love pinup art and have a few very dear friends that are artists, and they do that kind of work. One of them knew Fritz. Take care.
