SAN FRANCISCO - A 45-foot-tall sculpture of a nude woman that was scrapped from a plan to place it in Union Square earlier this year is back, but at a different location in San Francisco. The Unveiling What we know: The unveiling of the sculpture, R-EVOLUTION, is set for Thursday, April 10 at Embarcadero Plaza. The multidimensional sculpture, done by Marco Cochrane, appeared at Burning Man in 2015 and was also seen on the Las Vegas Strip as well as Petaluma. Officials said it couldn't be at Union Square because the 16,000-pound statue is too heavy for the square's tiles.
