None.
The sketch used for the design of the American Studies Group catalog on Woodward handed out at their
May 1970 exhibition held on campus in the school's Hilson Gallery is missing. We can't seem to find it and it may possibly be lost forever.
The closest thing we have to the sketch is the oil painting Four Maple Trees in March. However,
this sketch is pointing more to the right of Four Maple Trees in March, focusing more intently on the sugar house itself. Not to mention the sketch
has FIVE maple trees and a man gathering sap.
The Griswold House is a historical landmark across the road from Woodward's Southwick Home & Studio.
While the maples still stand to this day, the sugar house no longer does.
