We have recently opened the the rug which was left in my Aunt's house when she died. It measures approximately 14' x 10'. It seems to be in good condition except for a 2-3 areas of staining. I would like to know if this rug is of any quality or worth being professionally cleaned. Could you help me determine where this rug was made, if it is wool, or whether it is a premium rug with any value?
