This page is not mentioned in Finberg’s 1909 Inventory.1 The sketch, a small, upright rectangle in form, presumably represents a building or part of one. It runs almost into the gutter and is directly opposite the most prominent (albeit small) part of the irregular stub of a torn-out leaf, upon which there appear to be pencil marks, although they do not marry directly with the few strokes here. It seems that the present drawing was made as a continuation of whatever composition was removed from the book, rather than matching up to the drawing of Durham on folio 6 recto (D12325).
