Historical Relevance
As part of the Scott Falk collection, this is a fine example, the Jay in flight often said to have Jacobite significance. Superb condition and I'm sure Scott paid significantly more than today's market price, as far fewer examples were available in the pre-internet days on the 1980s.
In a historical context, this glass was hand-blown around the time of The Seven Years' War, a global conflict fought between 1756 and 1763.
