TWO VINTAGE JKW FINE PORCELAIN GAME BIRD PLATES

Two vintage bird plates are in excellent condition with no chips or cracks. One plate has a pair of pheasants and the other has a pair of grouse. Both plates have cobalt and gold around the rim. They measure 9 3/4" in diameter. Marked on the back with a crown and green shield "Fine Porcelain, JKW, Western Germany". There is black stamped lettering over this but I can't make it out. The pictures show a good description.
