Sensei Anko Itosu (with the glasses), pictured with some of his students including
Kenwa Mabuni (standing) & Gichin Funakoshi (to Itosu's left).

Date: c.1880.

Update - Having recently read an article on dandjurdjevic.blogspot.com it has come to my attention that Kenwa Mabuni can not be in this picture as he was not born until 1889, 21 years after Gichin Funakoshi. It seems likely that the boy seated is in fact Funakoshi though there is some doubt as to weather or not it is Anko Itosu sat beside him.
