Today, the Art Students League of New York and the Parks Department are teaming up to unveil eight giant sculptures in Riverside Park, along 59th to 72nd Sts. The project is called "Model to Monument," and a group of sculptors have been working on an intensive nine-month program to create the figures, which range from abstract figures of New York's past to a life-size bronze girl and her dog looking out on the Hudson. Riverside Park "provides the ideal platform to show these powerful examples of public art," said ASL Executive Director Ira Goldberg in a statement. Here's a look at some of the sculptures, which will be up for a year, and how they came to be.
