Delaware Art Museum, 2301 Kentmere Parkway, Wilmington, DE. My husband had a meeting so I was able to wander for as long as I wanted without worrying about him waiting on me. The museum has over 12,000 works of art. Many by local artists. One such artist is Howard Pyle. He is well known, especially for his illustration work. I was especially drawn to his painting "Marooned". There is a whole blog devoted to Howard Pyle here.
The Brandywine Museum also has famous artists from the area including the Wyeth family. As I was paying my entrance fee the nice young woman told me that a tour was just starting of the Andrew Wyeth galary hosted by Andrew Wyeth's only grandchild Victoria Wyeth. She was very enthusiastic in her presentation and gave lots of information only a family member would know. I felt really fortunate to have gotten there right at that time.
One of the paintings was the large painting "Snowhill" There is a very good description of this painting here. During the tour someone came within an 1/8" of touching this painting. You would have thought a baby was being dangled over a cliff by the reaction of serveral people. (Not that I think paintings should ever be touched.)
So that is just a little side-line about my trip out East. If you are ever in the area I highly recommend both museums.
