Vintage early 1950s, pulp science fiction magazine, "Astounding Science Fiction" from June, 1950. The cover story for this issue is "Incommunicado" by Katherine MacLean. This issue also includes sci-fi stories by Isaac Asimov, A. E. van 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 is a "6 0" in ink on the bottom edge of the pages.
