On this day, 26 September 1955, during a visit by dictator general Franco to Barcelona, underground resistance activist Francisco Sabaté hailed a cab and had it drive around the Catalan capital. During the journey he fired anti-regime leaflets through the sun-roof from a mortar he had assembled from inside his suitcase on the back seat. He reassured the worried driver saying “Don’t worry, I work for the government and I am distributing informational materials.” He later left the driver with a generous tip.
