The Mirror was purchased by my client online.
Many decorative mirrors can be found online at repeatable companies. A few of my favorites are.....
Anthropologie: Unique finds

Ballard Designs: European flare, quality for the price
http://www.ballarddesigns.com/wall-decor/mirrors/?
Horchow: Sophistication

Gumps: Unique Finds, Asian accents and Unique finds
http://www.gumps.com/decor/mirrors
Cost Plus World Market: Bargain pricing but some great accents finds
http://www.worldmarket.com/family/index.jsp?categoryId=3499257&ab=header:menu:homedecor:wallartanddecor:mirrors
www.overstock.com: world market section a and regular mirror section, large website of search through, but gems to be found!

Other places-local flea markets, salvage yards, re-sale shops, vintage shops and always the larger Cities have the Design Center (some open to the public) with the almost very your heart and home can desire!

hope this has been of some helps
all the best,
