I agree that the Perthshire is overpriced and optimistic.
But I don't think the price for the Delmo Tarsitano paperweight is unreasonable. The design was priced at $8,500 when it was exhibited in the Winter Garden Exhibit at the Alexander Gallery on Madison Avenue in New York City in 1984. It is called Dragonfly in a Strawberry Patch.
