Quien es "El Enojado", you ask?
The man on the bottle is my father, Pancho. In the mid-1950's he played in the Northern Mexican Liga de Béisbol, as catcher for the Tecate team. His penchant for arguing with umpires quickly earned him the name "El Enojado", or "The Angry One." The name stuck, and soon the PA announcers introduced him as such.
(...though he had quite the temper, he was quite well liked, and is a pretty good dude)
