At the Milliner's, dated 1882, is one of several pastels in which Edgar Degas turned his observational eye from the ballet to the Parisian millinery trade, a subject that let him study a woman absorbed in an ordinary act of looking and choosing rather than posing. Worked in pastel on pale gray wove paper — industrial wrapping paper, laid down on silk bolting for stability — the picture shows Degas experimenting with unconventional, inexpensive supports throughout this period, a practical choice that has since required careful conservation attention. It entered the collection through the H. O. Havemeyer bequest of 1929, one of the defining Impressionist collections formed in America. Scion treats a work's material history, including its support and any conservation record, as inseparable from its documented provenance.
