Overall very good condition with the exception of a series of small flake loss nicks to the edges of the foot rim, one small/minor indent/bruise to the top rim and one minor flake loss nick. Overall in our opinion this does not adversely affect the overall attractive appearance of the chair. The seat has been professionally re-upholstered – the brass hardware is all present and original. Overall this represents a rare opportunity to acquire a scarce chair.
