Congo Jack did not appear in more than a few issues of Lightning Comics in the early forties. This particular sequence, spread over two issues, has a science fiction setting in an underground kingdom. Congo Jack is kidnapped by green men because he is white. (The green men blow up the African tribesmen they first encounter, all part of the unconscionable racial attitudes of the day...natives were “expendable.”) There is a sinister green man who doesn’t want Jack getting the beautiful green queen’s favor. In the second part of the story some blue dwarfs enter the action. And action there is...Congo Jack is good with his fists and there is a lot of sock-bam-pow going on.
Mark Schneider, who signed both chapters in panels every couple of pages or so, is not credited with comics beyond about 1942. I assume he went into the Armed Services during World War II like so many men, but I have no verification. He was a decent artist, and his work fit in perfectly with the still young comics industry.
From Lightning Comics Vol. 2 No. 1 and Vol. 2 No. 2 (1941):
*This is the same Ace that published all of those cool science fiction paperbacks in the fifties and sixties, including the collectible and desirable Ace Double Novels. Publisher Aaron A. Wyn (born Aaron Weinstein 1898, died 1967) started in the pulp magazine business, was active with a comic book line in the forties until quitting that business in the mid-fifties, and is probably best known for the genre paperbacks, crime, romance, Western, and the aforementioned science fiction.
