Here in “Sluggy Freelance” a “Space Mummy” is introduced by a guest artist.
On This Comic’s News Sidebar the guest artist (who is a very talent cartoonist, in my opinion) says this of the character’s origins–
After going through several hundred uncataloged pages of Diesel Sweeties I concluded I wasn’t going to locate his version of Space Mummy.
But I know I’ve seen a space mummy somewhere before!
I think it was in a cartoon, vintage 1950s or 70s.
Speak to me of Space Mummies. What, where, when, why?
