The Municipal Art Society (MAS) is accepting nominations for the 2013 Brendan Gill Prize. Each year the MAS presents the honor, which carries a cash prize, to a creator of a work of art from the past deemed to embody the spirit and energy of New York City. Former MAS chairman Gill spent more than 60 years as a critic of architecture and theater for the New Yorker and the prize was established in his honor in 1987. Past winners within the field of architecture include Louis Kahn and Michael Van Valkenburgh (pictured).  MAS will be accepting nominations until January 6, 2014. (Photo: Courtesy MAS)
