Since returning to the addictive tumblr, one of the accidental collections I've made is of 1960s Batman photos. Given that the show only ran for a couple of years, the impression it left on popular culture is pretty damn spectacular. The tongue-in-cheekery is reflected perfectly in these stills, particularly the odd sight of Batman helping some kids across the road (or maybe it's the other way around?) and Burt Ward doing his best Fallout Boy impression. And I think it's fair to say that the Meriwether girls have the coolest mum ever.
