Can you call it a bust if it is eight to ten feet tall? I don't know a better description, so I will."Susan" is a big, white, fiberglass bust by Connecticut artist and sculptor Philip Grausman. She sits on the lawn of the West Hartford Art League, where she was unveiled just a week or two ago. Her surface is very smooth and she has a translucent appearance. I wonder if Susan will look as good when the pigeons discover her and when a New England winter does its thing to her.
