This is Thrilling Wonder Stories for February 1947, cover by Earle Bergey. The ISFDB entry for this issue is here. I found this version of the cover at Pulp Covers. Browsing the issue as preserved at the Internet Archive has turned up some interesting cover art, for example this by Virgil Finlay illustrating Murray Leinster’s “The Manless Worlds.”

And this uncredited piece (perhaps I’m more in love with the concept than the illustration itself) illustrating John Russell Fearn’s “Sweet Mystery of Life.”
