I found this photo in a book I was cataloging. I don’t get many books with photos, so it was kind of noteworthy for that, if nothing else. And then I saw this photo, taken in 1909. It’s of a “Rumpler-Taube,” an early German war plane meant to mimic the shape of a bird. The “skin” that would have covered the “skeleton” would have been painted with bird-like features.
