The O in the "LOVE" sculpture being lowered into place. It was cold and the skies leadenly forshadowed rain, but "LOVE" arrived monumentally in New York yesterday in time to gladden the city's face for Christmas. "LOVE," a five-ton sculpture by Robert Indiana, the pop artist, will be on display for the next six weeks at Fifth Avenue and 60th Street, at the entrance to Central Park, where it will be highly visible to midtown strollers and shoppers.
