Ceratile Marble Design (Bold Sand) by PT&P & Cambridge Tile – 1950s MCM – N.O.S. Posted on July 14, 2026 Cambridge distributed Ceratile for a while and, at least in this Marble design, manufactured Ceratile as well. The boxes say Ceratile by Cambridge and the backs of tiles are not marked with PT&P (except for one in this color).
