This is a white Royal Norfolk ceramic plate from Greenbrier International.
This plate measures 10.5" in diameter. A previous owner has made this a Giving Plate and glued on a piece of paper that reads "The Giving Plate: This plate brings kindness from home to home for everyone to share. Enjoy, refill, pass it on. Let the kindness never end."
This plate is in very good pre-owned condition and would be great for leaving cookies or other treats with a neighbor or friend.
