Denys Fisher a leading UK toy and game distributor decided to capitilize on their Mego Superhero line by creating a board game. The game only involves the DC heroes, across Town Palitoy cooked up a game based on the Marvel WGSH.
The character choices are interesting, Mr Freeze? This is probably the only time he appeared in anything related to Mego. Also check out Shazam, the artist obvioulsy just copied the Superman piece. I love his red hair and gloves on the front of the box. (Thanks to Ken for the character scans)
