Astounding Stories (21st Century Archives 1994 #25): The Mightiest Machine by John W. Campbell, Jr.

These are fridge (or wherever) magnets that we make out of trading, collectible, and game cards from the ’90s and beyond! Approximately 2.5″ by 3.5″ in dimensions, each card is attached to a slim (1 mm) magnet sheet, and ships in a clear polypropylene pvc/acid-free sleeve plus packaging. Stock images created from a single unit; individual units may vary slightly, depending on the cut and centering of the original card art.

All sales of back issues, grab bags, clearance items, and used collectibles are final.
