This issue is from March 1975 featuring "Search For The 'Impossible' Man" by Elliot S. Maggin and Curt Swan, plus a Private Life of Clark Kent story "The Kid With The Million-Dollar Smile!" by Martin Pasko and Curt Swan with Bob Oskner.  Graded in very good plus condition.

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.

Scans are of the actual comics.  I've been collecting since 1973, and buying & selling on eBay since 1998.
