This marquetry bookcase is firmly attributed to the cabinet-making partnership of William Ince (1737-1804) and John Mayhew (1736-1811) of Broad Street, Soho. The overall form, glazing pattern of the cabinet doors, and marquetry designs closely resemble those on a comparable breakfront bookcase from the Harrowby Collection, by Ince & Mayhew and possibly originally made for the 3rd Earl of Bute circa 1780. It is similarly constructed of harewood, satinwood, and rosewood marquetry (C. Cator & H. Roberts, Industry and Ingenuity: The Partnership of William Ince and John Mayhew, London, 2023, p. 282, ill. p. 225, fig. 7). A further example from Upton Grey House, Hampshire, is illustrated in a 1930s Moss Harris catalogue, An Abridged Introductory of Antique Furniture and Works of Art (p. 88, no. F9227). Furthermore, the marquetry ribbon-tied roundels on inner lower cabinet doors relate to those on a pair of commodes made for the Duke of Marlborough, circa 1780, and the marquetry urns with acanthus leaves seen on the outer doors of this bookcase are similar to the designs on a commode made for Lord Clive circa 1775 (C. Cator & H. Roberts, Industry and Ingenuity: The Partnership of William Ince and John Mayhew, London, 2023, p. 152, 158, ill. p. 314, fig. 172, p. 323, fig. 202).
