12 1/2″ x 12 1/2″ image on a 15″ x 16″ Bainbridge Board. This is a watercolor or gouache.
Signed Wm Esty, whom I believe is of the William Esty Company, only because that is the only William Esty listed on the Internet. It is logical to assume that Esty started off as an illustrator before evolving into a major important ad agency. Buyer pays for shipping.
