Attributed to Edward Lear (1812-1888) British. “The Harbury Cutting, Warwickshire”, with a Steam Train and Figures in the Foreground, Pencil, Inscribed on mount, Mounted, Unframed, 5.75” x 9.5” (14.7 x 24.2cm).
This is, in my opinion, highly unlikely as a Lear picture, though I would very much like it to be.
Here is a photo that is very similar to the drawing. Several more phots of the famous cutting. And here is its history. Also, information on how Isambard Kingdom Brunel “dug” the cutting: Lear mentions Brunel in an entry in his diary for 9 September 1859, when the Harbury cutting had already been finished.
