The Colorado Historical Society at 1300 Broadway in Denver, Colorado, holds a portrait of Joseph A. Thatcher dated c. 1899 by C. M. Carter. Thatcher was the first president of the Denver National Bank and a member of the Thatcher family of Pueblo, Colorado. That family had large cattle and banking interests in southern Colorado. Carter was a charter member of the Artists' Club in Denver and the club's membership list shows him as having a studio at 71 Kittredge Block in 1895.
