1886 woodblock print, Tanjiro Nakojima Kimono Pattern

Hello, This is woodblock print by Tanjiro Nakojima, a Kimono Pattern, done in 1886, I looked on the internet and he has a Kimono book of patterns in Museum in Tokyo! and a book of patterns at University of Michigan, of all places. It also says the Kabutoya Galleries, Inc. San Francisco, on label. This was open in the 60's and early 70's, and was one of the best in US. Fashion was important in every country. I bought this because it was a good price, but now I am happy, because I learned a lot about this, and my son is 1/2 Japanese, I will keep for him. Thanks for looking! What is little box with person inside?
