1920 Toy German jol Pumpkin Halloween Jack In Box Antique Big Mache Old Chaplin

I seriously doubt that this item was made as a unit in the 1920s. The box was made around that time but the item inside doesn't appear to be old. It is too bright, and lacks all of the characteristics of an authentic German item. In my judgment, this is a married item with no collectible value. I think the larger collecting community realized this, hence the ending price, a paltry amount if this would have been the real deal.
