The plate has a solid, well-balanced feel with a raised footed base and a hand-finished surface. A maker’s mark is present on the underside (see photos), consistent with vintage studio pottery production. No cracks or repairs observed; light surface variation and glaze character are consistent with age and handmade origin.
