Tom Scott Antiques has dated this piece to the 1860s.
The size of this mirror and the fabulous ribbons really does set this mirror apart from others.

The frame of the mirror has floral and leaf figuring with some of the base red gesso coming through the original water gilding and gives a wonderful effect.
Hopefully the photos will do this mirror justice, but I have shown it hanging over a chest of drawers to give you a sense of proportion.

Any queries, do let me know and if you are able, you are very welcome to come and see this mirror and any others I have from yourself.
Measuring:
48” or 122cm high
36” or 92cm wide
8” or 20cm deep at the ribbons
