Pith paintings typically depicted local subjects such as cultivated flora

dates I believe to the late 1800s

Handmade Multiplication Teaching Dial David Heger pot embellished with small circular mirrorsI love C. Weiman, presumably the parent, or perhaps the teacher, who made this excellent dial to make learning multiplication a lot more fun. Point the arrow, marked with a 7, toward a number then open the little window at the other end of the arrow to reveal the result of multiplying the two. And the result of multiplying 7 with the number on the opposite side of the dial is revealed underneath the "X" on the arrow. Great for kids, but pretty great
