Born in Buenos Aires, Solano López began his career in 1953 working for the publishing house Columba where he illustrated the series Perico y Guillerma.

[5] A success, El Eternauta came to the attention of the authorities as the series featured commentary of the political situation of Argentina and neighbouring Chile, prompting Solano López to flee for Spain to avoid possible arrest.

[2] In 1959 Solano López began working for Fleetway in Madrid and later London, producing artwork for a host of series, including Galaxus: The Thing from Outer Space, Pete's Pocket Army, The Drowned World, Janus Stark, and Kelly's Eye.

[4] In the late 1970s Solano López again fled Argentina following persecution from the authorities, and from Madrid he arranged the publication of both El Eternauta and Slot-Barr with the Italian magazines LancioStory and Skorpio.

[2] In the 1990s, Solano López produced work in the erotic comics genre, achieving hits with El Prostíbulo del Terror, from a story by Barreiro, and Silly Symphony, made for the magazine Kiss Comix.
