It looks like an art exhibit, when in fact it’s a family tree.

“The Richman Gifts: American Impressionism and Realism,” now at the Norton Museum of Art, is a window into how generations of early 20th century American painters influenced one another.

This collection of 11 paintings given to the museum — a “promised gift” from trustees Priscilla and John Richman upon their passing — allows you to follow how two schools of early American artists developed on different vines.
