Dulce de leche is Argentinian in its roots, translated, its name means “sweet from milk”. It is made by boiling large quantities of vanilla-flavored milk and sugar. In 2016 two brothers founded DDL & CO to offer traditional Dulce de Leche produced by local producers using artisanal methods. For their first advertising campaign, they wanted to find something new that had never been done before. So they addressed the issue of gender pay gap in Argentina by making the bill with a woman’s face on it worth 27% more than the one with a man’s face on it, addressing the fact that women are paid 27% less than men for the exact same work.
