Museum of Ceramics (old Post Office) Mural - East Liverpool OH In 1936 Roland Schweinsberg was commissioned by the Treasury Relief Art Project to complete a 15-foot lunette titled "Old Bennett Pottery Plant," which depicts the 1839 pottery of James Bennett, East Liverpool's first commercial potter. In 1937 the painting was installed in the post office building in East Liverpool, which now houses the Museum of Ceramics. The painting remains on public display and hangs above the door to the museum's archives and library.
