The cabriole legs carved with acanthus leaf, foliate ear pieces with punch work and claw and ball feet. Circa 1755.
These Chairs are carved with the initials of the maker ( H I ) on the underneath side of the back seat rail. Quite remarkably we had an identical pair that are now sold bearing the same initials to the seat rail.

A pair of chairs of similar design sold at Sotheby's New York 'A Celebration Of The English Country House' on the 16th April 2005.
