It seems probable that Middleton accompanied his tutor Henry Bright (1810-1873) on his tour of Kent in 1847. For drawings by Bright of Kent and Tunbridge see, M. Allthorpe-Guyton, Henry Bright 1810-1873 Paintings and Drawings in Norwich Castle Museum, Norfolk Museums Service, 1986, p. 78, 80, 81, nos. 50, 54 and 55.
As A. Moore, The Norwich School of Artists, 1985, p. 144, observes: '1847 proved to be the annus mirabilis of Middleton's life and career'; several watercolours of this date, and of a similar size to the drawing in this lot, are in the Norwich Castle Museum. The watercolours of Bullingstone, Kent, Alby, Norfolk, and Blofield are all illustrated by Moore, op.cit., pp. 142, 143, and 144 respectively.
For another drawing by Middleton of Tunbridge Wells see lot 126.
