Keramic tiles
A 1928 trade catalogue of ceramic tiles issued by the Cambridge-Wheatley Company of Covington, Kentucky, for architects and builders specifying faience and decorative wall and floor tile. The pictures are measured technical drawings with dimensions and section lines showing arches, jambs, and stone-patterned tile courses set out in grids. A designer could take from them the geometry of tile layouts, such as square-grid fields framing a curved arch and diagonal borders meeting at corners.
