Presenting an extraordinary fold-out supplement from The Illustrated Stock Doctor and Live Stock Encyclopedia, published in St. Louis by N.D. Thompson & Co. in 1880 — a rare surviving artifact from the golden age of American agricultural and veterinary publishing.

What Makes This Exceptional This magnificent fold-out plate contains nearly 50 separate illustrations meticulously detailing the progression of tooth development in horses — an indispensable reference for veterinarians, farriers, breeders, and stockmen of the era. Each engraving demonstrates the remarkable precision of 19th-century wood engraving craftsmanship, capturing the anatomical subtleties that governed equine health, age assessment, and valuation in an agricultural economy dependent on horse power.

Printed on delicate bank note paper — the same substrate reserved for currency and high-quality technical illustration — this piece reflects the seriousness with which publishers and the veterinary profession approached livestock care. The original folds attest to its authentic provenance as a working reference, designed to be tucked into the encyclopedia and consulted in barns, stables, and veterinary offices across the American frontier.

For the Collector & Connoisseur Whether you specialize in equine art, veterinary medicine, agricultural history, or 19th-century American illustration, this piece offers uncommon visual richness and historical depth. The sheer density of imagery — nearly fifty discrete engravings in a single, monumental sheet — makes it a standout display piece and a conversation-worthy addition to any collection devoted to the horse in American life.
