OK, Ok, I know that this cover is mostly Jack Kirby, but if you look very closely at the Eel, you will notice that he was drawn by the wonderful Mr. Ditko. I have always suspected that it was a Ditko insertion, and was recently backed-up when I checked the GCD and saw that Nick Caputo had note the same. There are plenty of covers from the period with Ditko inking Kirby in a way that gives the cover a truly Ditkoesque feel, but that slippery Eel is 100% Ditko. I wonder what happened. I know that there's a story behind just about Silver Age cover, and since this one isn't exactly Amazing Fantasy #15, perhaps it has never been recounted. That's too bad, as I'm always interested in the anecdotes behind some of the little oddities of comic book history. So, why not truly a Ditko cover, Steve did just enough one this one for it to make the cut.
