Spin-off merchandise from characters and subjects in popular culture are often just as fascinating as the characters, movies, radio programs, television events, or commercial products which inspire them. Apart from political pins, so-called "pinback" buttons or pins which display these characters and subjects are as old as the metal and celluloid buttons themselves. Beginning in 1893, people wore early plastic Heinz pickles to demonstrate their loyalty to that particular brand (as if home-made pickles weren't good enough!) and similar pins commemorate (and advertise) nearly every aspect of popular culture since. Comic strip and comic book super heroes are no exception; pinback pins adorned with hero imagery began to surge with these comics in the 1940s, and have not stopped.
From his first appearance in Detective Comics in 1939, Batman has remained a fan favorite in the world of crime fighting superheroes for over seventy years. This pin depicts the Caped Crusader and his faithful sidekick Robin, but perhaps most importantly, the highly coveted Batmobile.
