Okay, SotI isn't exactly a comic but it's a critically and firmly established part of comic history. The reason why I would've liked to have bought it when it came out is to be able to read it within the social context in which it was written. It's easy to look back on it now and point out the absurdities of Wertham's arguments, but I'd like to know what it was like to experience that first-hand, and to really see just how irriational people were being. For as much as I've read about that period, and for as cynical as I can get, I still can't wrap my head around just how insane things must have been back then.
