1950s Arithmetic Quiz Vintage Tin Toy by Wolverine. Made by Wolverine Supply of Pittsburgh. Push the handles on either side of the Arithmetic Quiz - left or right. There are dials (wheels) that will spin, and the math formula will be displayed in the window of the blackboard. The corresponding answer will be displayed in the small window above. IMPORTANT TO NOTE: This a vintage toy - so it has scuffs, scratches, and even a bit of rust. Cosmetic issues - to be expected from a tin toy of this age. Specifically note that this Arithmetic Quiz has THREE OF THE FOUR blue flaps, that are designed to cover - then reveal the answers. The toy works great! The dials spin with ease. This listing is intended as more of a collectible - rather than a toy for a child to play with. PLEASE REFER TO THE INCLUDED PICTURES IN ORDER TO UNDERSTAND EXACTLY WHAT YOU WILL BE PURCHASING.
