"Sketchbook bound in marbled paper boards; both covers are made up of scraps of paper pasted onto card; the marbled paper is folded over these so that both inside covers are partly obscured by it; Finberg conjectures that the book was home-made. (...)
As Finberg suggests, this book was probably in use during a stay with Turner’s uncle, the butcher Joseph Mallord William Marshall, at Sunningwell in 1789, though some subjects (folios 21 recto and 22 recto; D00038, D00040) indicate that it was also used nearer to London, and in London itself. With its drawings of Sunningwell Church, Nuneham Courtenay, Radley Hall, Isleworth Church and Lambeth Palace the book demonstrates that Turner’s main concern at this early date was already with architectural topography.
