This is one of the largest and most impressive silver plate mirrored plateaux I have ever encountered. It is 18 inches across (14.5 inches across the mirrored top) and the top is a full 4 inches above the table. The work on this piece is remarkable. There are several closeups so that this can be appreciated. The bottom is made of wood - always the sign of a quality plateau - and there is an English registration mark, shown in one of the pictures. This wonderful plateau will accommodate a large table decoration as the last picture shows. The piece is in beautiful condition.
