Vintage stereoscope - as is. The stereoscope has a few issues. It is missing one of it's wire card/photo holder pieces on one side. The velvet material along the face edge is only about a third there. The metal shows wear, marks and some sort of scuffing. Even with it's issues, the stereoscope still functions well. It is marked "The Mercury Stereoscope Trade Mark" on the metal and the underside of the wood is marked "Underwood & Underwood, New York". Please pm me for additional pictures.
