I could not locate a direct checklist, but here is what I found. I see information listing it as 1978 instead of 1979. COMC has active/sold listings [1]. PSA does not offer much help with population report [2, 3]. Some information regarding the "Mini" versions [4]. "Menko" information via blowoutforums [5], stating:
"The Menko set is called Kings of the Square Ring, which was produced for the movie of the same name. (photos come from the movie scenes, I assume). I believe theset has 20 different cards, each with 2 different backs.
The subjects in the set are:
- Benny "Jet" Urquidez
- Toshio Fujiwara (Kick Boxing)
- Willie "Bear Killer" Williams (Karate)
- Willem Ruska (Judo)
- Andre the Giant
- Bob Backlund
- Antonio Inoki
- Seiji Sakaguchi
There are also 2 other similar sets of the same name released at the same time. One is a Bromide set (sold in packs) and the other a "mini" set (has more cards than the Menko set)"

Does anyone have an idea of where I might find a checklist of this set. I'd really like to get it into TCDB, and I'm pretty sure there might be some trade interest, but I'm coming up empty, except for a few specific cards.
(Hopefully, I'm an idiot and there's something really simple I'm overlooking.)
