Illustrator Bill Nelson has become something of a fine artist, and rightly so. He has a magnificent feel for portraiture. Even in his early days this talent was evident by his great work with the legendary fan magazine, PHOTON, and the fun-filled MONSTER TIMES.
Here is an example of his work in the MONSTER TIMES. It's not clear whether the puppet was his idea or the editor's. Clearly, though, Mr. Nelson put as much detail into parodying his beloved monsters as he did his more serious work. The scan is big enough to print out and use.
