Antonio is also a well-decorated artist, with numerous exhibits hosted abroad, particularly in New York and Saigon.
Antonio's style takes roots from foreign artist Picasso. He had experimented greatly with colors to delineate his figures. His works' themes are taken extensively from folk genre. He is also one of the Masters of Modernism.
Antonio's more recent works see him moving toward abstraction, or a mix of the abstract and the figurative. He has been labeled both a modernist and an expressionist, successfully crafting an aesthetic that has allowed him to maintain his practice for over 50 years, exhibiting both here and abroad. He is probably one of the last pillars of Modernism, adhering to its core tenet of dynamic expression.
