Slovenian-born First Lady of the United States Melania Trump is being used to market English lessons in Croatia.
A photo of Melania Trump appears on a billboard for The American Institute, alongside the slogan "Just imagine how far you can go with a little bit of English".
Pictures of the billboard have been spreading through social media.
"The message is unambiguously referring to a person who, with a little knowledge of a foreign language, has become one of the most powerful individuals on the planet," Ivis Buric, author of the outdoor ad, told local Croatian news.
Brett Campbell, owner of the American Institute and an American living in Croatia, says the company wanted "a campaign that would remind people about the importance of speaking foreign languages and about the importance of this knowledge for international success".
