This drawing was sent to Marv Wolfman after he wrote to Bellamy in the late 60s. At the time he signed his name as Marvin Wolfman thus Bellamy's inscription.
Richard J. Arndt's excellent Marvel B&W Horror Magazines Checklist (hosted by Peter Brandt on the equally excellent www.enjolrasworld.com) says
"Marv Wolfman is now [September 1974] listed as editor (a job he’d been doing since at least #3 [October 1973])"
Marv made a request of Bellamy asking if he would be prepared to contribute to the Marvel Black & White range. Nothing came of it and sadly we didn't get to see Bellamy's take on those Marvel horror favourites!
