This is a photo of the original martial arts scroll of Matsumura Sokon. The photo shown here is from the website of Kuba Yoshio (or rather a branch dojo of his), an internationally acclaimed Okinawan 10. Dan Goju master. The scroll was exhibited in 2013 at the Prefectural Museum, as I noted here http://ryukyu-bugei.com/?p=1102.
