Incredible Hulk Annual #5 (1976) Groot
Incredible Hulk Annual #5 features the second appearance of Groot (of Guardians of the Galaxy fame). It is Groot's first appearance since 1960, when Groot first appeared in Tales to Astonish #13.
This is an underappreciated but surging Bronze Age key book written by none other than Chris Claremont of X-Men fame. It sports a Jack Kirby cover to boot. Heck, this book is almost 50 years old now! The book is square-bound and notoriously suffers from twisted, crushed, and out-of-alignment spines. This book has nearly perfect alignment and a nice, square spine, and it sports bright colors and gloss. It is graded 9,2 NM- with white pages by CGC.
