Ing-Rich Porceliron serving tray

15 X 10 1/2 " ING-RICH PORCELIRON SERVING TRAY w/ Daniel Webster quote. I received this item as a gift. Had no idea it might be something special until I did a google search and found the Ing-Rich company. Found a lot about the signs and licence plates but not much about these items. Would love to know the year it might have been made and its value.
