An important and rare mid 18th-century Chippendale period blue-and-white painted carved pier glass with the original rectangular plate, the cresting centred by a ho-ho bird, flanked by foliate topped turned finials, the pierced frame with foliate carved branches with a shaped and pierced apron centred by C-scolled pendent cartouche flanked with inverted urns pouring water. 
Many 18th-century mirrors were supplied painted and gilded, such as a pair of white and gilded pier glasses supplied to the Duke of Atholl at Blair Atholl, which are now overgilt. However during the 19th-century, however, mirrors tended to be re-gilded completely,  thereby diminishing valuable understanding of this type of 18th-century decoration. 
This pier glass is a wonderful discovery, as beneath the later water gilding the subtle original blue and white paint surface is perfectly preserved. Painted mirrors are known, with examples also in blue and white being supplied to David Garrick by Thomas Chippendale (1718-1779) for his villa in Chiswick.
