This early Copper Age key features the 1st meeting and team-up between Wolverine and Daredevil.  It's also a cool book as it features the first appearance of the scientist who figured out how to fuse adamantium to bone, and it explains the 5 different types of adamantium (the metal that makes Wolverine's bones so strong.  

This is a very nice copy of the book, with stunning color, nice corners, and great alignment.  It could be a 9.8!  However it was graded 9.6 NM+ with white pages by CGC.
