I didn't buy much at Philadelphia, and most of what I got was supply stuff. But I did find a great painting at Henny Staring-Egberts table. I bought it thinking it might go over the large enterance to the dining room (on the left), but the height of the opening meant that the painting ended up too close to the ceiling. But it worked out well over the smaller door which leads from the main hall to the parlor.
Sorry this post is so short!
