Doom building a time machine just to steal Blackbeard's treasure has yet to be topped in the entire comic book medium.

I'll never forget buying that milestone edition 27 years ago. The Summer was ending and I'd be resuming my 13 year prison sentence, better known as school. This was my first Fantastic Four by Stan Lee and Jack Kirby. And it was spectacular. It took my mind off the unpleasant fact in a week and a half I'd be in the last place on Earth I wanted to be.
In addition to being Dr. Doom's first appearance, it gave me an insight into what comics were like 30 years prior. It had the old ads, letter page, and ads for new things at the time like The Incredible Hulk #1 that were by then worth a fortune.
I must've read it a dozen times. To this day it's still my favorite issue of Fantastic Four. I remember asking myself then, why did they change a thing over the course of 30 years? That book was better when it started than it was then (Or ever again).
My favorite part is at the start Johnny Storm is reading a copy of Incredible Hulk #1. And he burns it. I bet he feels like a dunce now. I guess then Stan and Jack didn't give any thought yet to the concept of their characters ever actually meeting. more

Holding Sue as a hostage, Dr. Doom sends Reed, Johnny & Ben back in time to find Blackbeard's trunk of mystic gems. (Cover date: July, 1962)
