His work in the field of graphic design laid some of the foundations for graphic modernity in Catalonia. From his studio in Carrer de Tuset he made some outstanding designs such as the poster for the 4th Joan Miró Drawing Prize, in 1965, and the Galaxy alphabet, in 1964. In his sculptural work, he moved on from planimetry to three-dimensionality by using simple materials to create balancing, mountable tabletop pieces: a versatile world that Pedragosa called ‘optional geometry’.
