While we were writing the building description of this two-flat in the proposed Fairground Park Historic District in the O’Fallon neighborhood, we did a double-take. Is that…? Yes, that is. An owner of this striking building at 4147 W. Kossuth Avenue, built in 1916 by contractor J.W. Jones, covered the open false gable end in mesh to keep birds out. The neighboring building to the west has an identical feature, open, and seems clean. the two buildings to the east have identical features closed-in. So it goes.
