Holmes-style Stereoscope with Stereoview Card

This is a late 19th or early 20th-century Holmes-style stereoscope, an antique hand-held device used for viewing 3D images. The object consists of an engraved aluminum or light-metal hood, specifically designed with a scrolling floral pattern and a central circular motif that often contains a maker's mark or patent date. The hood features a distinctive red velvet trim along the edge that rests against the user's face to block light; this velvet shows significant wear and fraying consistent with age. The optical components include two glass lenses secured within the frame. The central structure is made of mahogany or similar dark-stained wood, featuring a sliding cross-bar mechanism used to adjust the focus. Attached to the far end is a wire frame card holder containing a vintage lithographic stereoview card depicting a coastal building or pier. The card is yellowed with foxing and corner wear. General condition shows oxidization on the metal hood, patina on the wooden components, and heavy wear to the velvet padding. This model reflects the mass-market popularity of stereoscopic photography between 1890 and 1910.
