When he finished high school, Farkash wanted to study journalism, but as Jews in Hungary were at that time banned from joining the university, he turned to carpentry instead.

In retrospect, the carpentry skills he later acquired saved Farkash from serving in the Russian front during World War II, and instead he was assigned to work as a carpenter in a military camp.

He then turned to Ephraim Kishon, also born in Hungary, who at the time worked for the Israeli Hebrew-language daily tabloid Ma'ariv.

This followed advice given to him by Ephraim Kishon, who encouraged him to choose a short and sweet name, though it was also a natural pick: as a student in Hungary was called "Lupus", the Latin word for wolf, by his teachers.

During the late fifties and early sixties Farkash worked as a caricaturist for the Israeli magazine Davar HaShavua where he used to draw daily caricatures.

Through the years Farkash supported and encouraged many young Israeli artists who attempted to enter this field, particularly children and teenagers.
