A Croatian language school has launched a new billboard in Zagreb depicting First Lady Melania Trump with the line: "Just imagine how far you can go with a little bit of English."

The campaign was launched by the Američki Institut, a centre for the promotion of American culture based in the Croatian capital.

On Thursday the centre posted on Facebook a picture of the billboard showing a painting by a local artist of the first lady in front of an American flag with the message: "We entered the billboard game".
