Born in Lleida, Francesc Graus moved to Barcelona to study at the Llotja School of Fine Arts and began working in the studio of Ricard Fàbregas.
After a stay in Madrid he returned to Barcelona, where he opened his own studio in the mid-1940s, later going on to combine his professional activity with teaching.
The bulk of his work consists of covers and illustrations for books and other publications, as well as tourism and event posters.
