A fun request, this guy collects rockabilly girls who are comic fans. Every sketch cover is a different girl and the artist gets to decide how to show their fandom of whatever comic/character they're on the cover of. We got Batman, and it's probably one of the easiest to do. After all, there's so much to do with Batman paraphernalia!
(And yes, her dress does say "na na na na na na na na Batman")
