Edgar Rice Burroughs wrote much more than Tarzan and John Carter...
...but not every concept "took off" and became a hit series!
Written by Burroughs in 1940 and published in 1942, the story is basically an updating of John Carter or Carson of Venus but set "present-day" and with no hope of return to Earth since his body was destroyed in the rocket explosion.
In addition, the world our hero ends up on is not the high-adventure fantasyland of Barsoom, but a technologically-advanced version of the Cold War between America and the USSR (with elements of Nazism) in the 1950s!
(There's an excellent piece about history behind the story HERE.)
Adapted by Marv Wolfman and illustrated by the highly-underrated Dan Green, this never-reprinted premiere from Tarzan #213 (1972) takes considerable liberties in condensing whole chapters into six pages.
The comic adaptation continued in DC's Tarzan from #214 to #218 and one issue of Tarzan Family.
There have not been any other comics or adaptations in other media to date.
