Not such a special drawing, but Rudy was sometimes a kind of a wild & aggressive guy, with whom I fought a couple of times myself (naturally he again attempted to beat me up after viewing this drawing). On the tatami, I stayed doing calmer Ju Jutsu, while he changed to the Karate clubs. During his first year for bachelor in Engineering (when I moved from Antwerp to Brussels to study at the Free University of Brussels) I heared from friends that he got on pills due to stress, and finally commited suicide.
