I don’t believe I’ve seen this hanger design before. Although this genre has limited appeal for me being much too hard to display, I do like the design - especially the book. There were several different designs all relying on the latticed honeycomb body. This is quite an interesting design. These were made in Germany in the early 1920s. It’ll be informative to see what this brings.
08/18 Update: This sold for a modest $117.50. I feel it should have brought more.
