This is a difficult German diecut to score in this near-mint condition. The Germans made several iterations of this general design in two sizes. This differs from the one shown on page 171 of my newly published reference not by the solid eyes and mouth, but because of the teeth. (Look at the same-sized example at the upper right [second photo] and compare that one's teeth to the one ziz is offering for sale.) The German diecuts have a surprising number of such subtle variations. In any event, this is a wonderful example, proven by the lofty price level this has already attained with over one week yet to go.
08/03 Update: This wonderful item brought an astounding $576, well, well, well higher than guide.
