Then of course there is Washington Crossing the Delaware.
There is a fascinating piece here as to how artistic license was given free reign with this subject.
Delaware is known as the First State and is famous for it's peaches. Peach blossom is the state flower.
The last piece of knowledge I added to my rag bag mind was the American Bald Eagle can be found in the upper Delaware River valley.
I am afraid I haven't had any artistic inspiration on this visit but I have enjoyed looking around.
