You can use it as a plate, or as a decorative plate for interior design ☺︎ I believe, based on my amateur research, that it is a ceramic from the Deruta region of Italy. There is a hole on the back, which appears to be original, and some blue scuffs. Please check the photos. Please consider this item with the understanding that it has been stored at home for a long time ☺︎ Thank you for looking.
