Just waded through this thread. Prices for these vases reach a high point arounfd the time of the Parkington sales in October '97 and April '98. Glass dealers have, in the main, never managed to achieve prices that were asked and occasionally received by non-glass dealers.
The explanation for this is likely to be related to the different clientel; collectors generally know the correct price range - others do not. It also relates similarly with decanters that have silver collars, etc., putting the item into a different type of market, ie. Objects d'art, rather than purely a collectable decanter that happens to have a bit of silver on it.
Despite Fielding's bullish estimate it would be more accurate to look in the price range £200-£400 IMHO. Still good, but somewhat more realistic, especially in the current market.
The dealer who has £645.00 on the ticket and who has had it for a couple of years is quite a tryer bucking the trend like that
As for psuedo-cameo
, this was the phrase used to refer to this type of glass ware when I first entered dealing 26 years ago. It has taken all this time, despite intervenning knowledge to correct. I suggest that it came about through someone latterly using the term and it catching on with collectors and dealers, and the mistake snowballed. Actually, I don't think it really matters how it arose, rather that we now use the right terminology.
