The Cos Cob art colony was a group of artists, many of them American Impressionists, who gathered during the summer months in and around Cos Cob, a section of Greenwich, Connecticut, from about 1890 to about 1920.
In a joking reference to their predilection for painting views of the vernacular architecture, group member Childe Hassam nicknamed the art colony "the Cos Cob Clapboard School of Art."[1]
