"Spanish Mackerel" fish plate is a design from the Rutherford B. Hayes Presidential Porcelain Service. Porcelain with enamels and gilt decoration. The colors were applied using chromolithographic and decalcomania processes. Afterwards, decorators painted the plate with enamel colors to add shading and to enhance the design. Finally, the edges were gilt. The plate is round with rippled and scalloped edges, and the lower half of the plate is molded in the shape of an open half scallop shell. The design, painted in an ominously stormy pallet of greens, browns, and greys, features a mackerel in the shallows along the shore, washed up by a rolling, frothy, whitecapped surf.
