Original 10.5x24" glossy paper sign has large image of Robin at left, pointing to image of Aurora's classic Batmobile model, complete w/small Batman and Robin figures in the cockpit. Promotional item printed for store use only by Aurora Plastics Corp. ©1966 NPP, Inc. Sign features same art that appeared on the second issue model kit (see item #2379). Robin's word balloon reads, "Holy Detroit! The Batmobile Is here!" and list original price of 98¢. Additional small text at bottom left reads "With Chrome-Plated Parts And (Gulp!) Batman And Robin!" Sign has three vertical folds (as issued) and some scattered handling wear/lt. aging but remains totally bright and glossy. Fine. Very rare and the first example we've ever offered. A must for both Batman and Aurora collectors.
