P[aul]. A[ndré]. Lemoisne. Degas et son œuvre. [reprint 1984]. Paris, [1946–49], vol. 1, p. 76; vol. 2, pp. 162–63, no. 319, ill., identifies the sitter as Estelle, and calls it a study for the pastel "Femme assise près d'un balcon (Mme René de Gas)," (Ordrupgaard, Copenhagen), which he dates 1872–73, suggesting that Degas may have been referring to that work when he wrote from New Orleans on November 27, 1872, that he had "spoiled a large pastel".
Louisine W. Havemeyer. Sixteen to Sixty: Memoirs of a Collector. New York, 1961, pp. 260–61, recounts the purchase of this pastel from Taigny through the art dealer Pottier [sic for Portier] in the presence of Mary Cassatt, for Fr 10,000 ($2,000); quotes Cassatt's opinion that it is "one of the greatest portraits Degas ever painted. His cousin sat for it and it is like a primitive".
Jean Sutherland Boggs. Portraits by Degas. Berkeley, 1962, pp. 40, 93 n. 80, p. 109, finds the sitter's eyes "too alive and responsive to be those of" Estelle, who was blind, and tentatively identifies this picture and the Ordrupgaard pastel as portraits of Mathilde; erroneously calls Mathilde the youngest Musson sister in the text, but gives her correct life dates in the index of sitters (1841–1878); notes that Degas did paint Mathilde, citing a letter he wrote to Tissot on November 19, 1872 [the letter states: "To make a cousin sit for you who is feeding an imp of two months is quite hard work"; Mathilde had a 2 month old son; published in Marcel Guerin, ed., "Edgar Germain Hilaire Degas Letters," Oxford, 1948, p. 19].
James B. Byrnes in Edgar Degas: His Family and Friends in New Orleans. Exh. cat., Isaac Delgado Museum of Art. New Orleans, 1965, pp. 38–39, 43, fig. 9, notes that the Ordrupgaard pastel is generally agreed to be a portrait of Mathilde Bell and that ours may be a study for it; also identifies a pencil drawing (collection Carol Selle, New York) as a portrait of Mathilde and calls it "certainly a study for the Copenhagen pastel"; compares these to photographs and portraits of Estelle, observing "except for the eyes it is not too difficult to understand why there has been so much confusion about the identity of the portraits of the artist's two cousins".
Ronald Pickvance. "Degas at New Orleans and a Drawing in Sweden." Connoisseur 161 (March 1966), p. 205, notes the close resemblance of the sitter and her pose in another pastel (Göteborg Konstmuseum, Sweden) to those in the MMA, Ordrupgaard and Selle works; observes that the pattern of the ironwork balcony in the Ordrupgaard pastel is clearly that shown in a photograph of the Musson house; cautions that "identification of the sitter in all these drawings must await more conclusive evidence from either photographs or documents".

Christopher Benfey. Degas in New Orleans: Encounters in the Creole World of Kate Chopin and George Washington Cable. New York, 1997, pp. 92–93, identifies the sitter as Mathilde; considers Degas' description of his cousin sitting for a portrait while feeding a two-month old baby a probable reference to the Ordrupgaard pastel [p. 96; see Ref. Boggs 1962].
Jean Sutherland Boggs in Degas et la Nouvelle-Orléans. Exh. cat., Ordrupgaard. Copenhagen, 1999, pp. 17, 19–20, 22, fig. 8 (color), calls it probably a portrait of Mathilde and dates it 1872–73; notes that Degas used pastel rather than oil for Mathilde's portraits to better evoke changing and ephemeral sensations; suggests that Michel Musson requested the Ordrupgaard pastel from Degas after Mathilde's death [see Ref. Brown 1990]; finds a suggestion of defiance in this picture, describing her face as more "précise," mature, and authoritative than in the Ordrupgaard pastel; interprets Mathilde's simple dress and slight smile as conveying supreme self-confidence.
