This scroll shows Master Jigoro Kano to the right, locked in combat with another student. I am not versed in the detailed history of Judo, and so do not know the person pictured to the left.
A short history provided by Wikipedia as follows:
Kanō Jigorō (嘉納 治五郎?, 28 October 1860 – 4 May 1938) was the founder of judo. Judo was the first Japanese martial art to gain widespread international recognition, and the first to become an official Olympic sport. Pedagogical innovations attributed to Kanō include the use of black and white belts, and the introduction of dan ranking to show the relative ranking between members of a martial art style. Well-known mottoes attributed to Kanō include "Maximum Efficiency with Minimum Effort" and "Mutual Welfare and Benefit."
One quote from Kano Sensei as follows:
Judo is the way of the highest or most efficient use of both physical and mental energy. Through training in the attack and defence techniques of judo, the practitioner nurtures their physical and mental strength, and gradually embodies the essence of the Way of Judo. Thus, the ultimate objective of Judo discipline is to be utilized as a means to self-perfection, and thenceforth to make a positive contribution to society.
I felt the dark Earth tone would complement the picture. This is accented with the white and gold ichimonji.
