Guess the artist: illustration for Adventure magazine

I know Blue Book magazine is the pulp that is supposed to have the best illustrations of all of the pulp magazines, and from the few 1940s issues I've read, I've no doubt that on average the illustration quality was much better than other pulps.

But I've also read Adventure in the 1940s and think that was an amazing decade as far as illustration quality. I know these weren't the peak days of the magazine, but the stories are still very readable, and most of the illustrations were quite good, and some are stunning.

I have here an illustration for a poem. Can you guess who the artist was for this amazing illustration? Leave your answers in the comments. I'll post the answer next week along with the poem itself.
