Not from MOTU Magazine, but I found this on the back cover of one of my old Archie comics, thought I'd share. Of course it's nowhere near the quality of art created for the magazine, but it's still fun. I expecially love the design of Castle Grayskull, one of the best ever imo. Skelly's slight armor and shin-guard differences are pretty cool too.
Plus, it's cool to see those vintage 8-bit screen shots! Enjoy!
