Radio KLA

Radio KLA broadcasts at 91.7 FM to the coastal resort city of Mar del Plata in east/central Argentina.  The following was copied off their website and run through Google Translate:

"KLA characters have their own life, self-esteem, are beings unleashed ideas, some strange. With music. Our music.
Every day for more than 10 years, from Mar del Plata, we emit a radio signal to all horizons.
news programs, magazines, humor, scholars in science, politics, soccer and religion, music fans, islanders, urban, surfers, stoners, lysergic, lefties, gorillas, Radicals and Peronists, merge under the same musical theme on Radio KLA.
91.7 Rock Radio KLA and Opinion."

They also broadcast at 104.7 FM to the beach towns of Carilo, Pinamar and Villa Gesell which are further up the coast from Mar del Plata.
Anybody know who the mustachioed gentleman who appears on all these stickers is?
