Here's a piece of strange bat-history! This is a 1960's Vintage Postcard advertising for "Color Dynamics," a local California printing company, inspired by the 1966 Batman TV show. The front features a full color promo photo of ( presumably ) the owners dressed as the Dynamic Duo, Batman and Robin. The reverse reads "POW! Holy Headquarters!!" and announces the store is moving to a new location in Saratoga, CA.
