Well, thanks for the effort anyway, paw broon.
It's just a shame that Bails' listing is so frustratingly vague on details, listing only the publisher (if that even) and year of activity, and NOT specific publication titles or issue numbers. The credit for TABU ("1940s") isn't very helpful even though I know that Tabu appeared in JUNGLE COMICS. Well, the one story at GCD that attributes credit to Brodie-Mack specifically is reprinted from a 1951 issue of JUNGLE, so I guess I'd need to check every issue of Jungle Comics published in the 1940s, looking for that "by Mack" byline. Going back to JUNGLE COMICS #1, I can see that
TABU, Wizard of the Jungle was created by Fletcher Hanks. Of course, like most features he created, he did not stay on it past the first year.
Even then, it seems dubious that an artist living in Australia was contributing first-publication work for an American publisher on some kind of regular basis. On KAZANDA, we know that it was reformatted and reprinted in RANGERS COMICS a couple of years after it had been published as a one-shot in Australia by N.S.W. Bookstalls, so that's clearly an unusual type of circumstance for Fiction House.
I also know that I can't completely trust Bails' data either, since he lists Kazanda as "c1939", when the work was definitely copyrighted in Australia in 1942. It hardly seems likely that the creators allowed the work to be published somewhere in 1939, waiting until a 1942 one-shot reprint to register a copyright on the work.
Studying the black and white one-shot a bit more carefully, I can see certain panels where Brodie-Mack took a decent amount of time to produce a lavish glamour shot of Kazanda, rendered in detail and with carefully-added gray tones. I can't help thinking in looking at these that he was working from a photo (or a live model, but probably a photo), and Kazanda's dress looks strikingly similar to the type of sarong worn by Dorothy Lamour in several films, such as
Jungle Princess (1936) or
Her Jungle Love (1938). There were several other similar roles she was cast in as well. I haven't been able to find of photo of Lamour where she's posed exactly like any of the images of Kazanda as drawn by Brodie-Mack, but I haven't spent THAT much time looking either. I'm just struck by the general resemblance of Kazanda to Miss Lamour, both in facial features and mode of dress, and can't help but think that she may have been the inspiration for Kazanda. Another possibility is Ann Corio, who appeared in
Jungle Siren with Buster Crabbe, but Lamour was certainly far better known, worldwide.
