Boston is an old city, by American standards, and most of its public art seems to be nearly as old as the city itself. “Boston often is criticized for lacking a bold or effective plan to develop new public sculpture. But some long-overdue appointments could change that. In May, artist Sarah Hutt was named director of public art for the city. Hutt now oversees the Boston Art Commission, which recently has been revived with an all-new membership. The four-member commission hasn’t been active since Director Mildred Farrell resigned two years ago. Even before that, the group frequently was criticized for a lack of discrimination and being out of touch.”
