This is Amazing Stories for January 1950, cover by Arnold Kohn. The ISFDB entry for this issue is here. I found this version of the cover at Pulp Covers. You can download and read the entire issue (missing its front cover, sadly) from the Internet Archive.
Great resource, that. In a couple of minutes, I even found an issue that printed a letter I wrote, way back when.
Indeed. In my IRL identity, I give as generously as I can to support the Archive, and I encourage others to do so as well.
