The work 'A T' by Antoni Tàpies, created in 1985 using the carborundum engraving technique, presents an abstract composition where red and black dialogue on a gray background. The dynamic red forms suggest movement and energy, while the black ones provide contrast and depth.

Tàpies, a key figure of Informalism, explored in this piece the relationship between matter and emptiness, inviting the viewer to reflect on the duality of existence. The characteristic texture of carborundum enriches the surface, making each glance a tactile and visual experience.
