This issue is from May 1975 featuring "The Man Who Created Superman!" by Elliot Maggin and Curt Swan, plus the Atom in "The Girl With The 24-Karat Dreams!" by Martin Pasko, Rich Buckler, and Klaus Janson.  Graded in fine condition due to wear and some light foxing on the back cover.

Scans are of the actual comic.  I've been 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 more Superman issues, 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.
