Format assumption is made based on the name of the club.
"UNDER the auspices of the Osaka Asahi Shimbun, a great Japanese daily, the Baby Kinema Club has been organized. This club publishes a monthly magazine, the "Baby Kinema," we are told by K. Senow, an enthusiastic league member, who promises us that the members of the Baby Kinema Club will also become Amateur Cinema Leaguers. The amateur movie world is fast linking together and American clubs will welcome films from Japan." (Gale 124)
