Boken Oh (Adventure King) Magazine produced this bookmark card and included it with an edition of their monthly magazine. While the date does not appear on this piece, we are speculating that it emanates from 1960, since the players are shown wearing uniforms from that season. The back is a grid in which the user was expected to fill in his/her school class schedule.
