Neiman Marcus Handpainted in Italy Extra Large Serving Platter GROUSE Numbered

Neiman Marcus GROUSE QUAIL Oval Serving Platter Handpainted in Italy Numbered M34 Extra Large 18" x 12" I believe this piece to be vintage but can't verify this Grouse or Quail graphic with desert grasses scene On under side edge, there are a few small places where glaze is off. I only noticed them when I ran my finger along edge. Unnoticeable.
