July '48 Astounding Science Fiction magazine, sci-fi rocket ship cover art

Vintage 1940s "Astounding Science Fiction" pulp science fiction magazine. This is the issue from July, 1948. This has rocketship cover art by Bonestell and the cover story for this issue is "Dreadful Sanctuary" by Eric Frank Russell. 

We don't know anything about grading pulp magazines, but this issue does have some wear and age. There are the initials "TG" in pencil on the front cover and the front cover is loose from the spine for about the bottom half. There is also a small number "1" stamp applied to the top right corner of the cover. There is a "7 8" in ink on the bottom edge of the pages.
