Vintage Deco Rectangular Sandwich Serving Plate / Tray. 13"x 6". c.1920's/1930's

This rather nice sandwich serving tray, which can of course be used for serving anything other than sandwiches, has no maker's mark but it definitely has a feel of having been made in the Art Deco period, 1920's or 1930's but it could be slightly earlier even.

It measures 12¾" x 6¼".

Lovely antique / vintage condition but showing some signs of its age.  Small black spot in the centre. See photographs.
