Double Sided 19th C. Mensuration Notebook Page with Watercolor Diagrams in Period Frame heavy chain someone would shovel it intoI just can't resist a pretty diagram, all the more so in watercolor on the page of an earlyish 19th century mensuration notebook, and even better in a terrific period frame holding two pieces of glass, so as to make the flip side with more diagrams visible on reverse. Lovely just to look at, but also nice to be reminded of how to calculate the area of a square, draw an angle from a quadrilateral, etc! Framed as found: 10 1 8" x 8 11 16 x 3 4. Paper: 6
