Hulk #1 is a late Copper Age key which features the first appearance of the Red Hulk (Thunderbolt Ross), and also the death of Abomination.  This is a cool storyline by Jeff Loeb.  This book was distributed at the ratio of 1 copy for every 20 ordered by retailers so it is pretty rare as far as late Copper Age books go.  The book is graded 9.6 NM+ with white pages by CBCS.  Alignment is perfect.
