For sale is a ridiculously rare Circa 1900 Tipp & Co Tin Litho Germany Wind-up The Little Calculator Boy Toy.  This does have a few noteworthy issues.  First, he is missing his left arm.  Next, the chalkboard is missing the little attachment in the middle.  Third, it does not currently work. Also, there is some pencil writing on the base as shown.  I have not tried to clean this toy.  This is a VERY HARD ONE TO FIND.  Please examine the photos to see exact condition.
