6609 Unknown – European School (18th Century) – Portrait of a Woman in Sepia Ink

Original 18th-century drawing in sepia ink and wash attributed to the European academic school, depicting a young woman in three-quarter view with refined features, ruffled clothing, and period hairstyle. The inscription “Mlle Bonthaux” suggests a personal or commissioned portrait. Executed with precise ink work and tonal modulation, the piece reflects the portrait conventions and draftsmanship practices of the 1700s.
