A Zander Production 

Jack in the Box is next to the last Ding to be located. In 2006, Jean Stewart, the collector with the golden touch, obtained the only known example of Jack from a yard sale find. The image below is Jack after a good cleaning. The second image is another yard sale find (not Jean) of what appears to be a prototype. Clearly the design is a Jack in the Box Ding A Ling but with significant differences from the final product. Lastly is an image takenfrom a salesman catalog. This too differs from Jean's example. Also, the slideshow at the bottom of the page has various views of Jack, most graciously provided by Jean.
