This may seem like an obvious choice, but I'll bet that many of you don't have this book in your collection. If that's the case - you're crazy! Detective Comics #500 is a giant sized piece of comic book perfection. I was an absolute Batman nut as a kid (still am) and this book just had so much to give. To start off, the wraparound cover is just soooo great. There is a wonderful history of cool covers for various Batman anniversaries, and this is no exception. It's great seeing all of the creators signatures right there on the cover. The main story here is 'To Kill a Legend' by Alan Brennert and Dick Giordano. It's amazing how few stories Brennert wrote, and how many have become classics. Giordano's artwork reminds you just how talented an artist he can be. This one has been reprinted a million times, but it's nice to see it in its original home.
Most of all, this book is a real treat for anyone feeling nostalgic. You've got a pulpy text story from Walter Gibson ("The Shadow"), a Wein/Aparo Slam Bradley story incorporating many nearly forgotten detectives, Joe Kubert back on Hawkman, Infantino drawing a decent Batman/Deadman team-up by Cary Bates and the always great Jose Luis Garcia-Lopez drawing a very fun detective tale by Mike Barr starring Elongated Man. This must have taken a lot of planning and it certainly shows. The real highlight for me, however, is the very simple yet very dramatic two-pager by Len Wein and Walter Simonson. 'Once Upon a Time' sums up everything that I love about Batman in a mere 12 panels - it's a sight to behold. All in all, this is just a phenomenal comic.
