Jose Tomás replied to my question about if the "Marching Soldiers" in display in the toy museum of Nuremberg might be the oldest preserved folds. Thank you Jose Tomás : )
JT: "Joan Sallas found some of the Senff's models in Dresden" Do you know the free ebook "An Origami Army of the Past" by Jens-Helge Dahmen? You can download it here: http://www.origami-shop.com/en/free-origami-ebook-xml-206_284_218_489-2554.html In pages 56 and 57 you can find different historic variations of the model and in what museum or classic book you can find them. Unfortunately the ones in museums, Nuremberg and Dresden, don't mention any dates. JT: "Also, Koshiro Hatori reported some Japanese models from the first decade of the XIX Century, from the Moriwaki family and some modeles folded by Kuzuhara Koto. May be them can tell us more about this." Did you find that information here https://doyouknowjapan.com/origami/ ? Guys, do any of you know a way to contact Koshiro Hatori or the Moriwaki family. I hope I'm not the only one really curious about those folds! Karen Reeds also replied. K: "The oldest preserved fold that I've seen is the traditional Seed Packet in the Linnaeus Museum/Botanical Garden, Uppsala, Sweden. http://www.linnaeus.se/link3.html It's very small and labeled by Carl Linnaeus himself (1707 – 10 January 1778) -- so it's at least 238 years old (...) I don't have a photo, but I know some of the people at the museum and could ask about getting one." Please do Karen! I can't wait to see some pictures and read anything they can tell us about that folded seed packet : ) K: "Norman Brosterman's collection might include some early 19th century Froebel and/or Pestalozzi kindergarten origami folds. Unfortunately, the wonderful images on his website don't give details about dates or provenance. His book might give useful leads". The website includes a contact form. I'll ask Mr. Brosterman if he knows exactly how old does folds are. Thank you guys for your very interesting answers. If anyone else has a candidate, please share it here in the list ; ) Cheers!
