A lush looking bunch of grapes if I ever saw one. This is one of three later 19th c. theorem-style watercolors of fruit I've just listed, found together in New Hampshire. I've bought and sold a number of watercolors of specific fruit specimens done in this manner--looking almost like airbrush paintings (and indeed these were likely done by blowing the color with a glass straw, then hand-painting the details.) With printed text identifying the specimens at bottom--in this case hardy and abundant Champion Grapes--perhaps they were done for a commercial purpose (fruit catalogue or orchard farmer's growing notebook?) but I'm not certain. Gorgeous. 

8 3/8" x 5 1/4" and in very good condition.
