John Hanley on Instagram: "Batgirl made her debut in the third season of the show, starting in September 1967. Her addition was an attempt to boost the show’s declining ratings. Due to the era’s views, Batgirl was typically only shown kicking villains rather than punching them, which was thought to be too aggressive for a female character at the time. #batgirl #barbaragordon #batman #batman66 #artcollector #oilpainting"
