I love the regency ebony and gold of the Portal Mirror by Restoration Hardware.  With convex shape and double frame making it 29 ½” overall, it is a generous size and interesting shape.   It somewhat reminds me of the convex mirror in the background of Jan van Eyck’s (Dutch Painter) “The Arnolfini Marriage” (in which if you look at the reflection you can see the artist himself-  tricky, tricky).
