I can not find other impressed numbers or marks with my 60 x microscope. Blue light shows no cracks or chips. There was probably a sticker on it at one time, most likely removed when it was framed, and this Black Forest/Victorian style frame is a gorgeous piece of hand carving, as you can see. The dimensions of the plaque itself are around 3 1/2" by 5" and it is inset in the mahogany wood frame that appears to have been made for it.
Carvings of grapes, fruit and leaves. The plaque is held in place with a thin sheet of mahogany wood that shows remains of very old artist type/masking tape inside the backing and some initials written in pencil which I assumed were of the frame maker. The outer frame dimensions are 6" wide by 7 1/4" tall, thickness varies from 1 to 1 1/4 and I put felt pads on back to protect the wall when hanging. There are no chips to the plaque and only minor expected wear along edges and here and there on the image.
A really wonderful version of this unusual portrait that has apparently been changed to reflect certain noble ladies.
