Marunouchi Mikai Bishi Tea Towel

[Maruni San's Bishi] In the 1925 edition, Masami Takeda, who was a high-ranking painter, wrote "Monsho" (a crest), "The shape of two equilateral triangles is a diamond" (geometric diamond). However, "Monsho" states that if you make a crest with this diamond, the height of the diamond is too low and it looks poor, and explains the following indexing method (Monsho no Bishi)...The Matsubakabishi and the Mikaishi are drawn from the geometric diamond, not from the diamond of the crest.
