Incredible Hulk #324 is an emergent Copper Age key!  It features the first appearance of the grey Hulk since 1962!  It has a killer Jack Kirby homage cover by Al Milgrom.  Doc Samson also appears in this story.  This book is graded 9.6 NM+ with white pages by CGC.  Alignment, color and gloss are all excellent.  A must-have for Hulk collections!
