This issue is from November 1972 featuring "Fury of the Energy-Eater!" by Len Wein and Curt Swan, and "Who Is Mr. X?" by Cary Bates and Curt Swan.    

Graded in fine condition as it has some stains on the back cover.

Scans are of the actual book.   Collecting since 1973 and buying/selling on eBay since 1998.

I do combine shipping...buy as many as you want and only pay the shipping amount on the single highest shipping amount in the item description (if you buy 5 items and all show $4.95 for shipping, you pay $4.95...I can send you an invoice or refund the excess back if you can't request an invoice). 

Please see my eBay store for hundreds more Marvel and DC Comics, including Jack Kirby's 4th World titles Mister Miracle, The New Gods, The Forever People, and Jimmy Olsen, and runs of JSA, Justice Society, and All Star Squadron, among other things.
