Two sumo wrestlers and a referee, silhouetted by a red sun-like orb. Yeah, that looks like the Japanese flag, I know. This was digitally synthesized from an illustration in a 1907 newspaper (thus totally public domain). The red circle was added for focus. The original article was informative but clogged with racial epitaphs of the day, and so it will not be quoted. None the less, enjoy this sumo-goodness.
