Antique Skeleton Key Illustration - Historical Locksmithing Art #3861490 (License: Personal Use)

This black-and-white line illustration depicts a vintage skeleton key, likely from the 19th century, with a large, rounded bow containing vertically aligned engraved characters (possibly maker’s marks or patent numbers). The shaft tapers into a traditional bit with stepped teeth designed to align with warded lock mechanisms. Fine cross-hatching adds texture and depth, typical of technical engravings from that era.
