A narrow brick building named Caskey Limited stood alone in a huge swath of vacant lots at 818 E. Ohio Street in Pittsburgh, Pennsylvania. Clinging to the surface of one of its exterior walls was a mural created not by urban street artists, but by generations of Pittsburghers who lived and worked next door in a multi-storied apartment building. When a wrecking ball demolished their apartments, a tracing of the interior rooms was left clinging to the surface of Caskey LimitedÕs adjoining wall. The details of this tracing are the subject of this photographic series.
