This is the finest form of the Chippendale swan’s neck (or scrolled) mirror.   This is not a matched pair, but a true pair, as each of the Phoenix birds face each other when hung and make a dramatic statement together.  Note the swan’s neck carving, with the leafage embellishments.  Also, the carved scrollwork flanking the mirrored glass.  It is the best and worthy of, for example, the Diplomatic Reception Rooms, etc.   This came out of a fine New York Collection.
