When Nicholas Dunphy did this etching in 1942 Happy Valley, now part of San Rafeal, California, was mainly a dairy. Roberts Dairy, located in Happy Valley, which is now the Montecito neighborhood in San Rafael, was a prominent Marin County dairy. It was founded by pioneer resident Rachel Armstrong Roberts, who started her business with two Jersey cows in 1898. Through her energetic work, the dairy grew to over a thousand cows in 1943.
Dunphy views Happy Valley from up in the hills of Marin county, looking down the valley toward the San Rafael - San Francisco Bay.
