The work 'A T' by Antoni Tàpies, created in 1985 using the carborundum etching technique, presents an abstract composition in which red and black dialogue against a grey 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 void, inviting the viewer to reflect on the duality of existence. The characteristic texture of carborundum enriches the surface, making each viewing a tactile and visual experience.
