If you're a fan of public art, or mosaics, or New York City, or transit, this could be your book. Contemporary Art Underground is a beautiful, weighty coffee-table book with photos from across the MTA universe, encompassing all boroughs (yes, and Staten Island too) and all of MTA's transit systems. The subway is front and center, but LIRR, Metro-North, and the buses are represented.

William Wegman's dogs lord over the 23 St F/M station; Yayoi Kusama has an impossibly long mosaic work running the length of the new LIRR station at Grand Central; Nick Cave's Soundsuits lines a new, narrow connector that links Times Square station to 42 St-Bryant Park.

Definitely worth a look, the book and the stations both.
