Adidas's latest Copa América advertising campaign has infuriated Colombians because it features an incorrect spelling of the South American country.
The German sportswear company's new ad for the Colombian football team's new home kit spelled the country as "Columbia" instead of "Colombia".
The ad - which features the national team's star players, including World Cup top scorer James Rodriguez - drew ire from Colombians on social media.
Adidas also misspelled Colombia on its website, but the gaffe has since been corrected.
One "very proud Colombian woman", who called herself Stephanie P, was so upset that she wrote an open letter on Twitter to the sports apparel company.
"In a world where ignorance is infamous when it comes to the acknowledgement of third world countries, it is unbeknownst to me why the correct spelling of COLOMBIA is so difficult to comprehend for the general public," she wrote.
Adidas apologised for the mistake and said it was working to replace the adverts.
The misspelling of Colombia is so common that it sparked the social media campaign #ItsColombiaNotColumbia in 2013.
