In the 1880s, Concho Avenue was the main east–west thoroughfare of the growing town, and these buildings date from this formative period. Merchants Schwartz and Frank (later Schwartz and Raas) built a wooden grocery store at 20 E. Concho in 1879, which was remodeled in 1886 by Oscar Ruffini into this one-and-a-half-story structure with cast-iron piers supporting a thick parapet of rock-faced coursed limestone. At number 26 is the former San Angelo National Bank (1879–1884) featuring a stone facade built by contractor J. C. Lillis. In between, the Schwartz and Raas firm hired Oscar Ruffini to design the one-story building (1885) at 22–24 E. Concho for merchants Johnson and Taylor. This was one of Ruffini’s first commissions in San Angelo. Johnson and Taylor went out of business in 1887, and the building became part of the Schwartz and Raas establishment, with an arched opening in the wall between the buildings and a rear extension linking the buildings. All three buildings have glass store fronts framed by stone or cast-iron-faced pilasters. Local preservationist Kenneth Gunter purchased all three buildings in the 1970s and restored them.
