Everett Fahy. Letter to Anne Poulet. August 29, 1969, confirms the attribution of this picture and its companion, Allegory of Autumn (69.155.1), to Boucher and assistants.
Hubert von Sonnenburg. Letter to the Wrightsmans. June 17, 1969, notes that the participation of Boucher's workshop in both paintings should be considered.
James Parker in The Wrightsman Collection. 3, New York, 1970, pp. 14–15, under no. 292 (Room from the Hôtel de Varengeville, Paris), ill. (installed above door), attributes them to Boucher with assistants, noting that each is signed and dated; suggests that the disparate themes of the two works indicate that they probably did not form part of the same decorative scheme.
Alastair Laing. Letter to Katharine Baetjer. July 9, 1989, from photographs, asserts that the "signatures and dates look authentic, so they are presumably products of the studio that Boucher was at least prepared to let go out under his name".
