Marked on the back with the Oneida logo, this little 6-inch tray was an award for something I don't remember in the 1970s. Very plain, but elegant in its simplicity. It always reminded me of the Victorian era when the parlor maid or butler answered the doorbell and extended a small silver tray for your calling card before announcing you to the mistress and escorting you to the drawing room.
Could be used as an underplate for a vase, a wine bottle coaster or just parked on a shelf for display. Some very minor scratches.
