Batman's (Adam West) utility belt from Lorenzo Semple, Jr. and William Dozier's Batman. Bruce Wayne wore his signature utility belt while moonlighting as crime-fighting superhero Batman throughout the series.

According to Batman historian Les Daniels, writer Gardner Fox first introduced the Dark Knight's utility belt in Detective Comics issue 29, published July 1939. In the decades since, the belt has become one of the character's most recognizable tools, and the source from which many of his other bat-themed gadgets - including such memorable components as his Batarangs, Batgrapples, and Bat-bolas - typically originate.

While the utility belts designed by costume designer Pat Barto for Semple and Dozier's series emulated the comic book originals by featuring a basic yellow paint finish, the final versions also incorporated military-style pouches in order to allow the storage of various props. This led to one of the show's most beloved running gags, in which Batman and Robin (Burt Ward) pulled increasingly specific yet unlikely tools from the belt. The gag proved so popular that it was later parodied in the Season 14 episode "Large Marge" of The Simpsons, in which Batman (West) retrieved a can of "Bat Carousel Reversal Spray" from his utility belt to save himself and Robin (Ward).

This particular belt comes from the collection of legendary model-maker Greg Jein. It is constructed from four leather straps painted yellow on front and dressed with static square and cylindrical wood storage pouches. The belt features a brass buckle engraved with Batman's bat insignia on front and affixed with a clip on the back. Also included is a color-printed still from the series featuring Batman in his signature costume. The belt exhibits minor oxidation on the buckle, chipping to the all-yellow finish, and folding at the edges of the straps from production wear and age.

Estimate: $40,000 - 80,000
