If Batman hung out in the Jazz Age, his headgear might look like this helmet built by the Ukrainian costume crafters at Bob Basset. This Dark Knight reminds me of Paul Pope's "Batman of Berlin." I imagine this Batman spends his time punching out bootleggers moving barrels of rectitude-poisoning Jokerbräu to Gotham's Tin Pan Alley, resisting the wiles of the Lindy-Hopping Tabby, and thwarting Mr Freeze's plan to weaponize the eyes of Doctor T. J. Eckleburg. (He'd rename them "the eyes of Doctor T. J. Iceburg," by applesauce.)
