This second archival volume collecting the Flash's Silver Age adventures was a lot of fun. Most notably, it features the introduction of both Wally West and Ralph Dibny. West, of course, nephew of Barry (Flash) Allen's girlfriend, became endowed with super-speed and took on the identity of Kid Flash. At first, Kid Flash's uniform was a miniature version of Flash's, and remarkably, he was not a sidekick in the same manner of Robin, Speedy, and Aqualad -- always at the side of his adult mentor. No, Kid Flash lived in another town and had his own solo adventures, usually the same length as The Flash's (12 pages or so). Dibny was a young man obsessed with India rubber men and was finally able to deduce how they gained their stretching power. Soon, Dibny was on the scene of many Central City crimes as The Elongated Man. In his one back-up, we learn that Dibny capitalized on his powers enough to earn enough money to be independently wealthy.
Major villains include Captain Cold, Grodd, Mirror Master, and the Trickster, along with some science fiction-type bad guys.
Iris West is her usual prim and proper girl reporter self, and often is waiting on Barry Allen to make their dates on time. There's very little character development with her, and she could easily be Jean Loring or Carol Ferris, to be honest.
So, anyway, fun stories by John Broome and Carmine Infantino from 1959-60.
