Mark Hunter, executive creative director at Euro RSCG London, said: "Fabio and Braulio have a passion for advertising that is evident the moment you see their book.
"Their work is fresh and surprising and above all else, beautiful.
"I am very keen to broaden the cultural and experiential make-up of the department here at Euro London and so a pair of talented and hungry Brazilians is just the ticket.
"I am extremely excited by the prospect of them joining our department."
