Aside of his figurative work, Antonio also has a deep interest in a more conceptual line of work in which, still using mostly  lost wax bronze casting, the repeated reproduction of an object, sometimes created by him, sometimes snatched from his immediate environment, creates a new form. 

Although these pieces start with the fascination with the chosen object and the symbolic significance that it carries or that Antonio attributes to it, soon the repetition and organisation of these elements creates a new dimension far from the original object.
