Antique Rare French Poupée by Léon Casimir Bru, Size 5 / Letter I c. 1875–1885
Léon Casimir Bru founded his Paris doll firm in 1866, and the poupée — a bisque-headed fashion lady doll — was his earliest and most celebrated product. The letter “I” corresponds to Bru’s proprietary alphabetical size code incised directly into the bisque, confirming a doll height in the 47 cm range.
