Just finished up Win Scott Eckert's Crossovers Volume 2 and had just as much fun with it as I did with volume one. In case you've forgotten, Crossovers is a massive listing of team-ups between fictional characters over the years in books, comics, television and movies. Volume 2 covers the period between the 1930s and the far future. Batman meets Daredevil. Vampirella teams up with the Catwoman. Bill Pronzini's Nameless Detective meet's Marcia Muller's PI Sharon McCone. Doctor Adam Spektor meets Doctor Solar and fights Dracula.
Speaking of Dracula, I noticed that the early to mid 1970s were absolutely chock full of monsters. The Comics Code Authority had eased up on the restrictions on using Zombies and Vampires after years of those subjects being taboo and suddenly Spiderman was teaming up with or battling Dracula, Frankenstein's monster, The Ghost Rider, Werewolf by Night, the Man Wolf, Morbius the Living Vampire, and so on. Then Dracula fought Werewolf by Night, Doctor Strange, and of all characters, the Silver Surfer.
For you Star Trek fans there's a big section covering the various Trek crossovers and fans of Lee Falk's the Phantom will see versions of the Ghost Who Walks teaming up with all kinds of historical figures and other comic strip characters.
Anyway, as I noted about volume one, if you're a fan of pop culture you need to get your hands on Crossovers. Hours of entertaining reading and you'll doubtless find stuff you'll want to track down and add to your collection. I know I did.
