This is Chicheley Hall, a 300 year old estate in Buckinghamshire, England, and it is the home of the International Science Conference Center of The Royal Society of London. Audubon was a fellow of this Society. You will notice the letters F.R.S at the bottom of all Audubon originals. These stand for Fellow, Royal Society. This Society chose Princeton prints to display along with their own Audubon originals. A jolly good recommendation!
