This is a poor reproduction of Ralph Dyer's Hand Painted Cachet for this stamp.  In spite of my best efforts, I've been unable to acquire one for my collection.  This image came out of the Mellone Catalog.  As you can see, it features the image of a cancer crab being stabbed by the American Cancer Society's Sword of Hope.  If you have a copy you are willing to part with, or know where I might obtain one, please drop me a line at smith@in.net.  I'm very interested in completing this collection.  Ralph Dyer created his first Hand Painted Cachets back in the early 1950s.
