"Paint and Beautify!" was the advertising slogan of YCO Paints in the 1930s--and the product proved to be quite successful. In the late 1940s, YCO even sponsored a basketball team--the YCO Painters that won several championships in the 50s and 60s from the Manila Industrial and Commercial Athletic Association (MICAA) basketball tournaments and from the National Open. Olympian Caloy Loyzaga used to play for the legendary ball team that was active till the 70s.
By the 1950s, Elizalde Paints and Wax was manufacturing the paints with the same popular brand name. The paint and wax products were actively promoted in women's magazines and Sunday weeklies. With the advent of TV advertising, its other product line--YCO Floorwax-- became a byword with its slogan "Sapak and apak, sa YCO Floor Wax". The only known advertising premium given away by YCO Paints is this small keychain that is a replica of a real YCO Mixed Paint can. Found in a Kamuning collectible shop, it dates from the 50s, the peak of popularity for YCO products that made life shinier and more colorful, for over half a century.
