Scarce Vue d'Optique of a naval battle. The engraving was designed to be viewed in a special apparatus that gave the view a strong 3-D impression. The title at top is engraved in reverse and another title is engraved at bottom for use outside the viewer. These prints were only produced for a short period of time, as they were replaced with the smaller steroviewer.
