Sometimes a building just says “look at me” before you know it and your eyes are captivated in curiosity and wonder. It was an icy cold January afternoon with a brisk breeze, on a walk south of Grand Street in Manhattan’s Lower East Side. The brick storefronts of the 19th century tenement buildings beckoned warmly, with their delis, cafes, boutiques, offices, and taverns. Then suddenly in the distance the Blue Condominium appeared, above most of the rest and flanked by a bright afternoon blue sky, as if the two were appearing in tandem.
