Juan Carlos Colombres (January 19, 1923 – July 6, 2017) was an Argentine caricaturist and humorist whose work has illustrated articles and editorials in a number of the nation's leading periodicals.

The pun, which played on the similarity between the name Perón and the Spanish word pera, prompted Jorge Palacio (who wrote under the pen name of Faruk) to urge Colombres to also adopt a pseudonym.

Asked for suggestions by Colombres, Palacio remarked that the satirist, who at the time wore a goatee, resembled the French serial killer Henri Désiré Landru ("Bluebeard," or as he is known in Argentina: "Landrú").

[5] Extending his satirical reach beyond print, he also led Jacinto W. y sus Tururú Serenaders, a 1958 musical group created as a parody of the Doo-wop ensembles popular at the time.

[2] His irreverent portrayals of General Juan Carlos Onganía (who had seized power in a 1966 coup d'état) resulted in the closure of Tía Vicenta by government edict in July of that year.
