Here's something aggravating:
The current prices for collectors' comic books are dependent on printing. A 1st-printing copy of Batman: The Dark Knight gets considerably more than a 2nd-print copy.
I bought my copy when the book came out at the Silver Snail in Toronto, as far as I can recall. Is it a 1st-printing? No idea. There's no COPYRIGHT in the freakin' thing, let alone a print number.
Why can't comic books have some of the same info as normal books get?! It's damned aggravating. Apparently you have to be some kind of Super Collector to be able to tell the print number, and that's not me.
But I'm selling the thing. That, and my Teenaged Mutant Ninja Turtles. And my Elfquests. And my Wolverines and X-Mens. So I gotta know!
