Missing: Amazing Fantasy No. 15 (not to mention some common sense)

Have you seen this comic?

A comic book fan in Nebraska apparently forgot one of the first rules of collecting: With great collections come great responsibility.

OK, we made that up.

But this is true: a $15,000 Spider Man collector's edition comic book is missing from a Lincoln, Neb., home, according to the Lincoln Star Journal. The newspaper reported:

The man said he had it with other comic books, but several people had been in and out of the house since he last saw it. 

Amazing Fantasy No. 15, the first comic to feature Spidey, sold for 12 cents in 1962. In May, a mint condition edition sold for $1.1 million.

And the guy left the comic where someone could just walk off with it? Well, we know it wasn't Kraven the Hunter because he's dead.
