You have to check out this amazing FM cover montage by Stephen Morrison! I'll let Steve give you a little background.
"I've been playing around with it on and off for awhile now, a tweak here, a small change there. Then it just sort of grew and like Dr. Frankenstein's creation, took on a life of it's own. It's still a work in progress, with hundreds of parts and pieces the combination and arrangement possibilites are almost unlimited. All the images are taken from FMOF covers, except the "4SJ Of Karloffornia" sign being heldup, that one came from a photo of Uncle Forry holding the sign he had taken down after his move to the mini Ackermansion. It probably (won't) appeal to the "purists", because I have altered many of the images, changing an expression a bit, mixing the hands from one image with another image, things like that. I tried to inject a little humor along the way. It was a lot of fun, and I was sometimes surprised how the image from one cover seemed almost made to interact with the image from another cover."
