Unfinished artwork is great fun to look at. It's as much fun as watching a Youtube of craftsmen or chefs at work - or the late lamented Bob Ross' painting show.
Often, a finished product reveals little of what went into its production. It is concealed.
Mrs. BD and I saw the show at the Met's new satellite gallery a few weeks ago. Worth a trip. You can travel the world, but olde NYC right here in little olde USA remains the premier fine art venue in the world. The tourists know that.
