ROBERT ARTHUR of THE MYSTERIOUS TRAVELER (autographed checks)
Robert Arthur was the co-writer of such radio thrillers, THE MYSTERIOUS TRAVELER, THE STRANGE DR. WEIRD, and other programs. He also wrote short stories for a number of pulp magazines and what you see here are cancelled checks with his signature on the back of the checks for some of those stories.
I only have two of these so unless you change the quantity to "two," you are purchasing only one of them. Sold on a first-come, first-serve basis.
Robert Arthur was also the editor of many Alfred Hitchcock Presents short story anthologies (it was he who wrote Hitchcock's introductions) and wrote a number of the ALFRED HITCHCOCK AND THE THREE INVESTIGATORS books.
