Gillows perspectives

The sketch on the right comes from Susan Stuart's article in the Journal of The Regional Furniture Society (2010) More about Gillows’ Windsor and Common Chairs  captioned: "A high back Windsor chair painted green, ash with deal spindles. Made by Joseph Wilcock, December 1806. Westminister Archive Centre 344/ 99, fol. 1804".

There are one or two other sketches of Gillows' Windsors which survive and they all seem to have this slightly curious 'bird's eye' view and I've never understood quite why they were drawn this way. Then I came across the photo on the left in the Courtyard Antiques sold archive.  The similarity is striking and rather pleasing.
