Here's what Jerry Bails had on the artist Brodie Mack
Interesting! I was not aware that Brodie-Mack is also attributed as having worked on TABU -- which was a
long-running feature that appeared in nearly
every issue of Fiction House's JUNGLE COMICS. Looking into this at GCD, all I was able to find was a single Tabu story attributed to Brodie-Mack, and that attribution came from a reprint in AC's MEN OF MYSTERY. Looking up the relevant reprint, I see it's linked back to its source as appearing originally in JUNGLE COMICS #134 (Feb 1951), yet the same credits don't appear on the GCD listing for JUNGLE 134. Looking at the issue here at CB+, it's credited on the original splash page as "by Mack"... but I can't really see a resemblance to the artwork from Kazanda there. I guess I'd have to go back and study the evolution of the TABU feature in Jungle Comics from the beginning to see if I could discern some point at which the artwork became more Kazanda-looking. Being that #134 is a much later JUNGLE issue, it may even be the case that that particular Tabu story had been reprinted from earlier in the run. Or it could just be a mistaken mis-identification with "Ted Brodie-Mack" being confused with an unknown artist who signed his work as simply "Mack".
The other thing noteworthy in Bails' brief summary is that Kazanda is attributed as "c(irca)1939" to both Australian comics, and to British comics. That certainly seems to allude to an earlier publication of Kazanda somewhere (perhaps even multiple 'somewheres'), prior to the 1942 N.S.W. Bookstall one-shot Australian comic book KAZANDA THE WILD GIRL AND THE LOST CONTINENT.
I'll have to look further into that "backup feature" Bails mentions in MARVEL COMICS from the years 1942-43. No, wait -- I just realized that Bails' listing of "Marvel Comics" refers only to the publisher of record, not to MARVEL
MYSTERY COMICS from 1942-43... which unfortunately will probably make it nearly impossible to nail down exactly which "backup feature" (Marvel published a LOT of those in the years 1942 & 1943) Ted Brodie-Mack may have worked on there. Searching for "Ted Brodie" or "Ted Brodie-Mack" on GCD isn't returning much in the way of relevant results, beyond Kazanda and that one Tabu story.
