Make Your O/O-27 Layout Look Bigger with this Built-Up Background Building Set. Transform empty areas along your layout or display with this new and improved background building set, designed especially for O Scale. For one low price, you get two fully assembled and prepainted industrial buildings, ready to install on your railroad. The City Litho Company is a two-story building with a street level roll-up door, while the Black Rock Beverage building stands three stories tall. They're typical of structures found all over America and will fit perfectly on any layout. For additional realism, a cardboard insert with printed interior scenes can be placed behind the windows if desired. Best of all, the narrow profile of these buildings allows them to be used almost anywhere space is limited. Or, use them to smooth the transition from 3-D scenery to a printed backdrop.
