The Germans issued three sizes of this deeply embossed articulated skeleton design during the 1920s. The size you will see most commonly is 27" high. This intermediate size is rarely seen, while the largest, at ~50" high, is exceedingly rare. Prices for the German diecut skeletons have been strong for some time. The seller has not provided enough photos, with none showing the reverse, so that will almost certainly impact the final price. Given that the most common size brings ~$150, this should bring somewhat less than double.
