Caballero is a Dutch brand of unfiltered cigarettes owned and manufactured by British American Tobacco (BAT).
Dutchmen, mainly from the artistic parts of society, promoted the product (Ramses Shaffy and Henk van Ulsen, who later claimed he never smoked, were a few examples).
A song was also created by the Dutch amusement band Leedy Trio, called "Ay-ay-ay!
The move turned out to be a success, increasing Caballero's market share from 4 to 36% in just a few years, also thanks to the effective advertising campaigns with the famous "Mexicaantje" ("Mexican" in English).
Caballero sponsored the cycling team of Jan van der Horst from 1962 until 1972 and participated in the 1970 Tour de France under the "Caballero-Laurens" name.
