Spectacular Spider-Man #25 (1978) Carrion
Spectacular Spider-Man #25 features a Keith Pollard cover and containing the first appearance of Carrion. White Tiger and Masked Marauder also appear. This under appreciated and undervalued book is graded 9.8 NM/MT with white pages by CGC. It's rare, too, as there are only 29 9.8's in the CGC census!
