I always find it unbelievable that people can have something like that lying around and not know about it. Just like those stories of people who just throw stuff out without checking with anyone if they might be worth something.
Maybe it's just that I'm Dutch...
America is mad about first appearance books of superheroes btw. It's why I'm holding onto my two copies of Witchblade's first appearance. You never know what they might do twenty years from now.
I'm not that into the collector's side of it though, I mostly just buy trade-paperbacks because importing all those floppies is simply too much of a hassle and an expense.
But hey, that's extremely cool for those people.
