He held his first solo art exhibit at the Luz gallery in 1961. His drawings, collages and constructions are revelations of a free spirit, a highly discipline mind and precision-motivated craftsmanship. His sculptures and installations are minimalist structures built from ordinary objects, often philosophical, as he challenges prevailing norms and concepts of society. He initiated the CCP Thirteen Artists Awards to recognize and encourage young artists who invent new approaches of art making. This pioneer and guru of conceptual art in the Philippines have nurtured a generation of young artists in new vanguard art practice. He received both the Republic Cultural Heritage Award and the Araw ng Maynila Award for Painting in 1972. He was one of the awardees of the CCP Centennial Honor for the Arts from the Republic of the Philippines in 1999. He currently exhibits at the West Gallery, the Finale Art File and the Manila Contemporary.
