Very unusual recessed plate with vase for use as a centerpiece or punch bowl. There are also four cups that go with this that I will include. Acid etched satin glass with amber cased and cutback Greek Key design and rim design(like elongated egg and dart) on the underplate or tray. Very heavy and solid....with just a small chip on the vase as shown. Shows appropriate use/shelf wear to base for being about 100 years old. The underplate measures 15 1/4" with the vase or bowl being a substantial 8 3/8". We believe this is Pairpoint/Mt Washington as very similar patterns can be found on shades and similar production in the 1880s-90s.
