The painting was done in Valdemosa, Majorca, where they were spending an autumn. Sargent's older sister Emily, is in the chair (foreground) reading a book, with their friend Eliza Wedgwood, a member of the famous porcelain manufacturing family, on the sofa (background), either reading or writing a letter.
Eliza said of it, "Sargent painted in oils such an amusing picture of Emily and me--in what John called 'Garde Mangers,' Emily's invention for keeping out mosquitoes."
