On this winding "Door Tour," hitting every stop from hip Williamsburg to elegant Sutton Place, the soul of New York City is revealed through this most unlikely medium. The remarkable row house doors, warehouse gates, extravagant entryways, and even construction sites documented here represent the people, culture, and attitude of the "City that Never Sleeps." From welcoming to ominous, brazen to bleak, astonishing portals can be found in quiet neighborhoods in Queens, graveyards in the Bronx, and small stores in Manhattan. More classically beautiful doors adorn the homes of some of the wealthiest and most powerful people in America. Gorgeous entrances to hotel lobbies lure you into luxurious interiors. In Brooklyn, graffiti artists turn industrial zones into studios, doors into canvases. Allan Markman opens the door to a visual jam session of urban architecture, but you must walk through it yourself.
