View between the paint corridors from one instrument to the other. The models in glass domes sit out of of the line of flight.
There is a new edition of Peter Cook’s excellent book on drawing, “Drawing, The Motive Force of Architecture”. It also includes an additional section with, for instance, a wonderful new Mark West drawing, Smout Allen’s composite drawing/model for the Egyptian Museum, a couple of Perry Kulper’s finest and some of Marjan Colletti’s Metalika drawings. And another of my drawing instruments in action. Well worth a look!
