The collection was formed by Lynne and the late Philip Blaker of Austin, Texas, and many of the pieces were purchased during trips to England in the 1980s-90s. It features a variety of different forms including opaque- and air twist-, balustroid- and facet-stemmed examples.
Five 18th century opaque-twist glasses from the collection, two with engraved decoration to the bowls, are estimated at $100-400 apiece.
Also shown here is a single 7in (18cm) high trumpet bowled glass set on a Newcastle light baluster stem with an acorn knop which has an estimate of $300-500.
The auction house points out that because of the ongoing Covid-19 crisis this auction will probably be held with remote bidding only. An official announcement will be made early this month.
