This, I believe. is a shop or salesman's sample of a mosaic pattern design featuring Henry Chapman Mercer's "Knight of Nuremberg" tile of a Medieval knight on a charging horse set in a pattern of brick-like tiles from the Moravian Tile Works of Doylestown, PA. Measures about 15" long, 11-1/2" high, and 3". It weighs about 11 lbs. Overall it is in good condition for its age. There is a section of grout missing along the bottom edge of the left tile. Both tiles are in great condition. Th...e tiles are a yellowy ivory color with a gray-blue outline and a subtle, fine crackle in the glaze. The sample is set into a pine framing box with a dark stain and a hanging wire and eyelets which are of recent vintage.
