Ellery Queen's Mystery Magazine for April, 1951 - Vol 17, No. 69.

This is a special issue for Magicians. At the start of every story, add the digits of the page number, for example page 25 would be 2 + 5 = 7, and the 7th word on the page would be "problems." This is true for the first page of every story. On page 86 add 8 + 6 = 14 and the 14th word on the page is "problems." On and on. The magazine is in good condition and complete with some wear and yellowing on the pages. A neat magician's collectible.
