Cheese platter in antique faux-bois slurry, and its matching knife

The slurry tray is in perfect condition, no accidents, no cracks, no splinters. The enamel is very shiny, with barely a few traces of wear on the tops of the reliefs, barely visible. The coin is marked on the reverse, hollow under enamel of the faiencerie brand, in the form of a small coat of arms containing the initials l.a. The blade of the matching cheese knife is made of stainless steel, the handle in slurry also. French production of the first half of the twentieth century.
