VTG~LINOLEUM FLOORING~LARGE PIECE~75″X85″~1950-60~MOVIE SET~MCM~GRAY GRID A
This piece is not marked. It has a black backside. I have 2 pieces of this design. I wash all pieces front and back with a floor cleaner and let them dry in the sun. This piece was salvage, cleaned and rolled up until I could deal with it.
