An extraordinary and exceptionally rare collection of original copper-mounted orthopedic radiographic teaching plates from the professional archive of Dr. John Otto Dirlile (1893–1950), a World War I-era physician and medical professor. These early 20th century medical study plates depict anatomical and skeletal radiographic imagery used for orthopedic instruction, publication, and professional reference during a formative period in modern medicine.

Each piece exhibits authentic age, archival wear, handwritten physician markings, and original mounted construction consistent with professional academic and medical use. The richly toned copper surfaces possess a striking industrial elegance, blending scientific history with museum-quality visual appeal.

Acquired directly from the Dirlile estate, this remarkable grouping represents an uncommon surviving example of early orthopedic radiographic teaching material — an elite acquisition for collectors of antique medical artifacts, dark academia, scientific history, or rare physician archives.

A truly distinctive and investment-worthy collection seldom encountered outside institutional holdings or private medical collections.
