New Yorkers who have occasion to visit the Lower East Side — on the way to the Tenement Museum, perhaps, or Essex Street Market — may have noticed a towering mural on the corner of Allen and Broome streets. The painting is a silhouette of a sleek woman with high-heeled boots, a windblown coiffure, and what appears to be a gun. Just adjacent to the painting is the Emma Peel Room, an imbibery that a stray millennial tells me is “aight” in terms of atmosphere and libations.
