Jaguar Man is one of my new favorite characters. And this is his only appearance! :(
There were two one-shot issues of
ALL GREAT COMICS. One was "published" by William H. Wise & Co., Inc. in 1944, and one "published" by Chicago Nite Life News Inc. in 1945. Both ran 132 pages, selling for 25¢. They both also starred Fox Feature Syndicate characters, so I'm guessing they were actually
produced by Fox.
Anyway, Fox did publish a second Jaguar Man story (in
ZOOT COMICS #2 [Summer 1946]), alas it was a somewhat different character. In
ALL GREAT COMICS, Jaguar Man's real name was Steve Lane and he had a pet jaguar named Ebony, while the
ZOOT Jaguar Man was known as Murray Mane with a pet jaguar named Ja-Go. Don't ask me, I dunno, I've never seen it, I've just
read about it. Interestingly, both tales are credited to "Jack Lane."
As for why the logo of the story reads simply "Jaguar"... I don't know that either.
