What is a Muhammad ali vs superman comic book worth?
You'll need to refer to the Overstreet Comic Book Price Guide .
He may have appeared in ads for Baseball equipment , like the popularily circulated (Mantle and Mays) bat and ball sets. Sporting goods were not banned in comics advertising, though I doubt a direct Superman Tie- in. On the other hand there was a Superman-Muhammad Ali team- up in I believe the ( Brave and Bold) a comic book that speciallized in Team-ups of usually two characters who normally did not work together.
