Duel To The Death With The Vulture; The Uncanny Threat Of The Terrible Tinkerer | The Amazing Spider-Man #2

We meet the first classic Spider-Man villain: The Vulture. Like all great Ditko villains, he seems created just for the cool visuals. He looks distinct and cool (or at least intriguingly odd), he's smart, he's mean, and he will be back.  And... there's also a second story! The tale of the Tinkerer. It is... an ungood story. Seems left over from the old Amazing Fantasy bin. But the art is great, and it gave future writers a good challenge to try to retroactively make this story fit into the universe.
