This is another example of 'The Firm's' early Reformed Gothic work, from the early 1860's. Designed by Morris's friend Phillip Webb, this piece clearly showed Webb's indebtedness to the Reformed Gothic of Pugin.
The dressing table mirror can be tilted and locked in position with a dowel.It is available in Oak (shown below) or black finish as originally ( the black version has gold bandings on the lower front rail ). Made to order.
Above LH photo shows a Philip Webb chair from the same period as the dressing table mirror. You can see the cross-over influence with the black finish, and gold banding on the backs dowels. Interestingly Morris was still using this treatment 30 years later in the great hall at Wightwick Manor c1893.
