I realize that it looks liked the Used Magazines Patrol is coming for this lady, but really it’s a Robert Gibson Jones cover for Amazing Stories, December 1945. An interior illustration by Julian S. Krupa and accompanying text makes what’s going on clearer.
This issue of Amazing Stories is available to read and download from the Internet Archive.
In case there are folks like me who are bothered by the rubber stamp defacement on the artwork, I’ll point them to the lower-resolution but much cleaner example of this cover art that you posted back in 2017:
