I love seeing rare and visually compelling items populating the generally drab Ebay listings - and then to find such an item being sold by a premier seller - just makes the treat that much richer. There were at least two variants the Germans created in the 1930s of their basic skull and crossbones design. One is this one being sold now while the other, with a plume, can be seen on page 178. Both are valuable, with sustainable guide values of $525.
10/29 Update: The end of the season is drawing near and lots of money has been spent, making the great items listed this late end at relative bargain levels. The buyer scooped this up for a mere $404.99.
