Portrait of John Brudenell-Montagu, later Marquess of Monthermer (1735-1770), half-length, in a red coat and blue mantle

The present work can be compared with the portrait, previously thought to be by Anton Raphael Mengs but now attributed to Thomas Jenkins, of John Brudenell-Montagu, later Marquess of Monthermer (1735-70), in the collection of Lord Montagu of Beaulieu (see F. Russell in the exhibition catalogue Treasure Houses of Great Britain, Washington, 1985-6, no. 174.) The few minor differences between the present portrait and the Beaulieu picture, and the canvas dimensions which suggest the work was executed in Italy, would support an attribution to Jenkins.
