The original version of the logo was a simple black bat against the grey color of the batsuit. Variations of this design have been used since the character's first appearance until 25 years later. In 1964, Detective Comics #327 introduces the Bat-logo as a yellow ellipse behind the insignia against the grey color of the batsuit after Julius Schwartz decided that the symbol with the yellow oval would make Batman look more contemporary.
