The role of catcher Bruce Pearson for fictional baseball team the New York Mammoths brought De Niro into the spotlight as an actor, while the film Bang the Drum Slowly didn't garner any Oscars, it's still worth a watch for any fan of De Niro or baseball. A nice flannel cap is always a good pick-up for Fall, and true fans can get this replica Mammoths cap made by Ebbets Field Flannels.
