I was at my friends house and snapped this picture on my iphone. Needless to say, every ivory (and most likely every pearl) is a unique piece. The pieces have not been removed from the board so we don't know if the backs are blank. However, most of the pearls have serial numbers and are from royalty (as noted by the crowns). The frame is huge, maybe 4.5' by 6'. A most unique and fabulous collection.
