In Central City (1933) Ronnebeck employed intersecting lines and planes in a vignette of the historic mountain mining town founded in 1859 during the Pike?s Peak Gold that came to be known as the ?Richest Square Mile on Earth.? Visible at the top of the lithograph is St. Aloysius Academy which was torn down in 1936. Structures in his vignette were also depicted in Boardman Robinson?s lithograph, Midnight Central City (1932) and Eve Drewelowe?s watercolor, Central City (1940).
