Iron Fist #12 is written by Chris Claremont and drawn by John Byrne.  Killer Captain America and Iron Fist battle on the cover with art by Dave Cockrum.  The Wrecking Crew appears, too.  This is one of the most popular issues in the run, and it is not easy to find, especially in this grade.  We couldn't find one on eBay.  This book is graded 9.6 NM+ with white pages by CGC.
