Description
This is a fantastic color-litho. and engraved trade card for C.F. Zimmerman Co. (out of Dolgeville, NY) for their ‘Autoharp patented May 9th, 1882, with New System of Figure Music’; this is a printers’ proof of an advertising trade card folder, because it has the printers’ centering marks in each of the white triangles, the white rectangle at the bottom where the local seller’s name would be is blank, and the inside of this oversized two-page piece is completely blank as well.
