Here's a couple of great old Stan Lee & Steve Ditko tales, can't remember where they were first published, but I'm pretty sure they're both from Amazing Fantasy.  The I, the Gargoyle! one I'd never seen before.  I remember reading the Howard Purcell version, from Silver Surfer # 7, when it was reprinted in one of the old British Marvels, back in the day.

Cool Stuff.

from Secrets of Sinister House # 13. from The Incredible Hulk # 139.  from Strange Tales # 84.
