Tom Scott Antiques has dated this piece to the 1920s.

The two mirrors are very close in size, so if they were to hang as a pair of pier mirrors or alcove mirrors for example, it's not terribly obvious one is slightly different in size to the other and the colour tone difference also works well together.

As you can see from the photos, there are some areas where the finish has worn through which I have left as it adds to their originality. Both mirrors have been fitted with new mirror glass, so there is no blemish or foxing at all.
The dimensions below are shown for both mirrors and priced as a set.
Left smaller:
35 1/2 inches or 90 cm high
26 inches or 66 cm wide
Right larger:
37 inches or 94 cm high
