The ones that really got you hooked on comics?
As a young boy in the late 70s, my dad brought home a garbage bag filled with comics...

Jack Kirby Captain America
Jim Shooter/George Perez Avengers
Steve Gerber/Sal Buscema Defenders
Chris Claremont/John Byrne Marvel Team-Up
Jim Starlin Captain Marvel
