I 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 still even if you've mastered your multiplication tables!
In great structural shape but there is some clouding to aging to the wood/clouding to the finish, as shown in photos. Signed on the back. 12 1/4" in diameter; each layer of wood measures about 3/8".
