Andre Gray put plenty of research into the extraordinary tattoo he unveiled to the world this month.
The Watford striker has had a number of the most iconic leaders of the civil rights movement inked onto his back - a process which took 72 hours to complete over nine separate sessions.
Political figures such as Martin Luther King, Nelson Mandela and Malcolm X feature alongside reggae musician Bob Marley, world heavyweight champion boxer Muhammad Ali and the famous podium protest involving athletes Tommie Smith and John Carlos at the 1968 Olympic Games.
Gray called the artwork a 'masterpiece' when he posted a greyscale portrait of his full-back tattoo on social media last week, and rightly so.
