This may be the hugest story key in the Marvel Universe. The death of Gwen Stacy was a major turning point in Peter Parker's life and a total shock to all Marvel readers at the time. This copy looks great, except that somewhere down the line the cover got folded over in a stack. Very high grade otherwise.
Grader notes:
large crease front cover
light finger bends on cover
light spine stress lines to cover
