Great mid 19th century Bohemian ruby engraved glass plate with 8 different hand engraved spas. These were purchased during the Victorian Grand Tour era....this is particular to about c1860. Getting harder and harder to find these finely engraved examples. This example is particularly nicely engraved, and I know....I have seen 1000's. Excellent original condition...no chips, cracks or repair but there is one open air bubble from the making. Very nice work and superb for display. Measures just under 8" diameter. Cut and polished large pontil on back as shown. Completely hand cut and engraved.
