German Single Harpsichord. Beautiful. Made from cherry wood with walnut keys and cherry sharps. We were told it was a Eric Hertz. But I can find no marking or stamp. We have a letter from Eric Hertz to the previous owner discussing a cover for this harpsichord. It has what looks like a small water mark on the corner of the lid. I included a pic of the mark. Besides that, it is in great condition, no cracks.
