Have you ever forced Robin to eat a handful of rats because he was getting lippy with you? Then you need the flatbilled Batman The Dark Knight Returns 9Fifty Cap! Made from 100% polyester by New Era, the Batman The Dark Knight Returns 9Fifty Cap is based on the famous Frank Miller story...the one where Batman fights Superman. Not the one where Robin eats rats. That's a different story and I don't think that one has a snapback hat based on it...yet.
