We're big fans of Anton Furst's design for the 1989 Tim Burton Batmobile. Did you realize he was also responsible for the swooping design of the Batwing in that movie? Well, it looks like the logo, so he's responsible for saying, "Hey. Let's make it look like the logo."
Quantum Mechanix relied on reference documents from the Warner Bros. archive to recreate the Batwing in tiny scale as a keychain. They tell us they disabled the mini guns, missiles, and lasers "for safety reasons," but we all know why. You'd be out there doling out tiny justice if you could. It's best not to tempt you.
