This is one huge chunk of a collection. There's a little over 500 pages of Silver Age Wonder Woman reprinted here, in black and white. To be perfectly honest, they're only worth reading for hardcore Wonder Woman fans, or fans of the Silver Age in general. It also has the first proper appearance of Wonder Girl, back when she was still just a teenaged Diana. She must have been very popular right away, as nearly every issue after her introduction had a Wonder Girl side story.
