Back in Spain, Gil entered as graphic designer in the Hispavox recording house, becoming shortly its Art director. He then worked for two other record labels, namely the Spanish branches of Ariola and RCA.
In 1966, Gil moved to Alianza Editorial publishing house, where along almost thirty years he produced more than 4,000 book covers that made him the best known and recognized Spanish graphical designer.
