This is a Silver Age gem of a book.  It has the first big-time Leader cover.  The Leader is a major Hulk villain and in our opinion this is the best book to get, other than his first full appearance in Tales to Astonish #63 (which doesn't feature Leader on its cover).  Written by Stan Lee and drawn by Herb Trimpe.  This book is graded 9.4 NM with white pages by CGC.  It has nice alignment and gorgeous color.
