I haven't seen one of these come up for sale in some time. This slot-and-tab candy box was made by the Dolly Toy Company of Dayton, Ohio under their Fibro Toy line. The items were produced sporadically between 1934 and 1953, much less regularly than the witch pulling cart and cat pulling cart Fibro Toys. These are never marked for some reason. They have not yet been reproduced. It'll be fun to see what this brings!
08/14 Update: This brought a healthy premium to guide value: $338.33 versus $250.
