This issue is from December 1978 featuring "Will The Last One To Leave Mercury Please Close The Planet?" by Len Wein, Paul Levitz, Joe Staton, and Dick Giordano and "A World For The Winning!" by Len Wein, Joe Staton, and Murphy Anderson.  Graded in low-grade GOOD condition due to water damage on the lower portion of the book, but it is complete with all pages attached at both staples.

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 $5.95 for shipping, you pay $5.95...I can send you an invoice or refund the excess back if you can't request an invoice).

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