My father purchased a zither at a garage sale. We have been trying to figure it's name/stlye & approx. age and value. It resembles the elegy and concert zithers, but it has one large opening in the center and two smaller openings off to the side. The large center hole has a picture of George Washington, a house with indians surrounding it and a picture of an angel. It's seems to be in fair condition and is only mission one string. Thanks for help.
