Wonderful French architectural manuscript on 'Perspective'. This appears to be a student's own manuscript and sketches from an architectural or art course. All of the contents are dealing with perspective in different forms. Some are purely mathematical (such as the design and sketches of cones and other shapes.) Others are examples of sketches drawn in proper perspective. The portfolio contains a large number of loose leaves. Each aspect (text in French) has one or more illustrations following. Many (but not all) of the pages have pencilled numbers to the top edge. In total there are 48 pages of text and 64 pages of illustrations / diagrams. In fact, there are a few more, but we have only counted "significant" pages. The paper is a little darkened, and there are a few very minor closed tears to the page edge. The folder has cracking to the spine edge, and is darkened, and at least one of the ties is still functioning. The front has a tipped on printed illustration with the title. An attractive and fascinating piece. 330 mm x 255mm.
