Sandby spent much time in the environs of Windsor and did many drawings of the Wood Yard. Curiously, and without any apparent explanation, almost all of Sandby's drawings of the Wood Yard are signed and dated 1792. Occasionally, Sandby made experimental works in which he combined the two media, as here, of oil and gouache. In this work the effect is far from successful. There is general discolouration, and the image, especially in the foreground, tends to disappear into the canvas. The use of canvas is rare in Sandby's work: invariably he used paper and card as support. He was a keen observer of the human condition at all levels, and did many studies of workers at their daily activities.
