Passing through Philadelphia this week, today was a fine day–full of heavy clouds and steady drizzle–to visit the new exhibition of American still lifes at the Philadelphia Museum of Art. Arrayed in a generous space, it was easy to follow the curators’ concept for the display. This was not a day to be out in the rain more than you had to be, but some workmen in front of the museum were busy putting up the Christmas tree. It was quite an undertaking, with cranes, trucks, and cables. One could see that, were this tree to topple, it would be quite a to-do. But there were no mishaps, and gradually holiday lights are appearing all over the place!
