The Amazing Spider-Man Annual #20

I remember reading this comic very vividly. I'm sure we all have that particular story or issue which may have effected or touched us in different ways. This was one for me. Truly a tragic story and when I read it, I was just a kid traveling in the back of the family vehicle on a road trip to Florida. My Mom was kind enough to let me purchase several comics for the road. Comics were comics. Funny, exciting and silly. But this one was shear tragedy. From what I know of time travel in the MU now. Nothing would have stopped this event from coming to pass. Still. This is when I knew that sometimes there are no happy endings. When I realized I have been enjoying the drama of these comics. With an ending so encompassing, such personal loss and failure. It will make your heart sink.

This ranks up there as one of the most memorable stories I've ever read.
