Oh, I have seen it before. I asked people about this crane. They said that it is folded in educational origami widely, for children or seniors who are difficult to sharpen the edges. And someone told me that he had folded 1000 crane in 1980s this style. I'll gather more information and tell you soon. Sincerely, jassu from Korea
