Pair consists of very large mc 2" porcelain enamels set into brass frames w/2.5" dia. Reverse brass shank and threaded screw make for a length of 2.75". These English-made items were produced for the American market in the early 19th century, generally known as Battersea enamels. Similar examples are shown as Hake Washington 3001 and 3003 but typically these are offered as single units, not a matched pair, and unusually only in three colors while these are mc w/delicate shading on the facial areas. Most importantly, the typical size is 1.5" dia. while these are impressively and significantly larger at 2.5". One tie-back has .25" tarnish spot on rim and 3/16x.25" surface flake off the right middle bkg. removing just a sliver of pale blue paint but well away from the image. The other tie-back is flawless. Extremely rare and highly desirable, almost never seen in this large size as a pair. Exc.
