Antique Skeleton Key Illustration - Historical Locksmithing Art #1928335 (License: Personal Use)

This meticulously engraved illustration depicts a traditional skeleton key with a decorative heart-shaped bow, a slender shaft, and a multi-toothed bit designed for warded locks. The fine cross-hatching and linework suggest a 19th-century technical drawing or catalog plate, emphasizing both function and craftsmanship. Such keys were commonly used in domestic and institutional settings before the rise of pin-tumbler mechanisms.
