A fantastic 18th Century Watercolor by one of the two architectural Masters of their time, Robert and James Adam. Correspondence with several museums in London and Scotland as well as the annotations on the reverse all point to an authentic masterpiece. " The Picturesque style, perspective view, composition, use of foliage, use of grey wash and badly scaled staffage are all characteristic of the draughtsmanship of both Robert and James Adam as well as the draughtsmen in their office.· The draughtsmanship is of a style that it may very well be in the hand of Robert or James Adam (more like Robert than James) but there is not enough here to ascertain this with any certainty. Certainly the foliage and staffage in the foreground are comparable with a great many drawings in Robert’s hand. For the above reasons, I would suggest that it would be appropriate to state that this drawing is ‘attributed to the Adam office’ -Do let me know if I can be of any further assistance.With best wishes,Fran Dr. Frances SandsCurator of Drawings and BooksSir John Soane’s Museum13 Lincoln’s Inn FieldsLondon WC2A 3BPDirect line: 020 7440 4265Frame: 18x 22 Drawing: 14.5 x 10.5in.
