Men of Tomorrow: Geeks, Gangsters, and the History of the Comic Book

I see that this isn't coming out for a couple weeks, but I was reading an advance of it at my stepmom's place over the weekend. It seems to cover not the actual comics so much as all the semi-shady business dealings that went on over the decades, i.e. who really created, wrote, and drew the early Superman and Batman comics, who jacked the rights, who sued who, etc. Not my favorite aspect of comics, to be sure, but one of the early chapters on all the uncredited ghostwriting/drawing then went on before any sort of system was established was interesting.
