One of mine?
Bomba has a long history. He started off as a series of young boys adventure novels back in the 1920s. A not-disguised-at-all Tarzan clone, Bomba grew up in the Amazon, and his later adventures shifted to Africa. Bomba had 20 books over 13 year period, and then he vanished.
Not that I necessarily want to read the books. According to the Wikipedia article, "a common theme of the Bomba books is that Bomba, because he is white, has a soul that is awake, while his friends, the dark-skinned natives, have souls that are sleeping." Errr, OK.
But nothing vanishes forever in American pop culture, does it? Because a movie studio made a long series of B-movies about Bomba, starring Johnny Sheffield, who had played "Boy" in the Tarzan movies. So, not typecast at all, eh, Johnny?
The 12 movies ran from 1949 to 1955, and their popularity caused the books to be reprinted. But then Bomba vanished again.
But as I say, nothing can stay the gaping maw of American media hungry for intellectual property to sell to us. The movies were chopped up and re-edited into a syndicated TV series call Zim Bomba in 1962, and apparently became something of a hit, despite having only 13 episodes.
Which brings us to DC. In the late 60s, DC was trying to take advantage of the burgeoning Baby Boom market, by plastering teens in unusual situations everywhere. The Anthro series started up shortly after Bomba, for example. Teen jungle fighter, teen caveman, teen president...DC was going to sell us teens, no matter what!!
I've never, ever seen an issue of Bomba anywhere--quarter bin, legitimate back issue bins, anywhere. The only reason I even know of the series' existence is DC house ads (usually on the same page as an Anthro ad!). And it certainly is unlikely to ever be reprinted, as the rights are no doubt long gone, and probably too expensive to re-obtain just for reprinting a forgotten 7 issue series that no one in the universe has heard of.
But look at the pretty art!!! Check out that Carmine Infantino/Charles Cuidera cover of issue #1 above. And starting with issue #3, Jack Sparling took over cover and interior art. I've always been a huge fan of his 60s and 70s work for DC. Just take a look at these covers (click to embiggen):
So, DC...
