Antoni Morillas is an integral part of the history of graphic design in Spain. He was a founding member of Grafistas FAD and one of the few Spaniards to be accepted as member of the AGI (Alliance Graphique Internationale) [club of the world's leading graphic artists and designers]. He belonged to the generation that looked abroad during the postwar period, and helped to make the profession of designer what it is today.

This booklet collects the sketches preserved by his son Lluís Morillas. They are indispensable documents to understand the constant formal exploration of this pioneer of Spanish design.
