This is a great advertising mirror for Bournville Cocoa by Cadbury’s   
The mirror is bevelled, and showing a small amount of age in the glass. The frame dark and simple a bit like the cocoa. 
It would have hung in the grocers shop or general stores, to advertise to you their wares, whilst also being able to check that your hat’s on straight. 
Measurements: 42 x 2 x 52cm high
