April 18, 2007 - Metal Sculptures in Madison Square Park

I found this info HERE:

STAINLESS-STEEL TREES TO NEW YORK PARK

A tree has gotta be tough to make it in New York City -- but stainless steel? New York artist Roxy Paine is installing three new sculptures made of the shiny
weather-proof metal in Madison Square Park at East 23rd Street in Manhattan, May 15-Dec. 31, 2007. The works include Conjoined,
a 40-foot-tall sculpture of two trees, the branches of which connect in midair; Defunct, a 42-foot-tall sculpture of a dead or dying tree infiltrated by
fungus; and Erratic, a stainless steel boulder measuring 7 feet high and 15 feet wide. The project is sponsored by the Madison Square Park Conservancy and James Cohan Gallery.
