His work The Mute (1973) and his preparatory drawings (1972) from the same work become part of the Museo Nacional de Bellas Artes collection. Elba Pérez says:

“It was no lack of boldness of the members of the Asociación Amigos del Museo Nacional de Bellas Artes to purchase The Mute . The piece represents the torture known as “submarine” which is said to have been invented in the 30’s by the police superintendent Lepoldo Lugones, the son of the homonymous poet. In The Mute, the control of the metaphoric possibilities of the polyester occurs. The overwhelming presence of the work is imposed from the rotundity of the mass, an articulated block in sharp planes. The anatomic and postural distortion is taken to the limit and it is governed by plastic reason only. It is a stiff being, of welded limbs by the pain of the torture; on the back, his arms and fists attached, merge with the spinal column that is projected on the violently contorted face. The clear resin stresses the condition of torture, the water coagulates where he has been submerged. The cold tones and the marble textures complete the testimony given”.
