Cinema advertising was Dan Libor's steppingstone to a future career as a "serious painter". He started early. He was still a teenager when he was hired as cartoon painter in the early 1960's. His colleagues during those days were the young Ephraim Samson, Loreto Racuya, and Freddie Villanueva - all of which made names for themselves later on as serious painters. 

Libor was born on Paril 26, 1946 in Pasay City. He majored in Painting at the University of Santo Tomas College of Architecture and Fine Arts after college, he was hired by Ideal Theater as Operation Manager in charge of lobby displays. As such, he was obliged, together with his helpers, not only to conceptualize and paint movie ads, but also to fashion 3-d giant replicas of movie monsters.
