Does anyone have any info on this unique 3 panel oak dressing mirror? It is about 7 foot tall and the wing mirrors are 20" wide. It is heavy..It also has a small  curved shelf about a foot up from the  bottom... I would like to find its value and what it might have been used for, a home or business....Thanks for any info you have....The photo of the mirror is on this site under  3 panel oak dressing mirror......
