1940s sci-fi magazine pulp cover, Astounding Science Fiction, Isaac Asimov

Vintage 1940s pulp science fiction magazine, "Astounding Science Fiction" from November, 1949. The cover story for this issue is "...And Now You Don't", by Isaac Asimov. There are also stories by Robert Heinlein, A. E. von Vogt and others.

This is in nice vintage condition. We don't know anything about grading pulp magazines, but this issue does have light wear and age. There are some pencil marks on the covers (mostly the back) and there is also a "11 9" in ink on the bottom edge of the pages.
