Only noticed after the cover was attached to the comic how much I stretched out the logo on this custom. Oh well. I might re-do it but am reluctant to mess up another original copy. I also replaced Dr. Doom with Baron Mordo for the lower box. The Baron Mordo image is from his Marvel Value Stamp, which can be found in Supernatural Thrillers #9.
INSIDE FRONT COVER

INSIDE BACK COVER

I always use the original back cover on the customs.
