Who's this clean cut dude? Looks like he just stepped out of a Biblical epic of the 50s. Yes, that's our man from Cimmeria, on this cover from 1949. Interesting what artists could get away with in those days before Frank Frazetta and Barry Smith got ahold of him.
CORRECTION: After I wrote the above, Fred Blosser advised me in a comment that this is not Conan after all, but another character in the tale. Thanks, Fred. Pretty sad when Conan doesn't even merit the cover on his own story.
