I thought Lucas was one of the staff of the museum when I saw him sit in a black chair in the corner, chatting with a visitor.
He studies animation and often comes to the British Museum to do some sketches. He said it was relaxing for him. It was not his first time to be mistaken for a staff member - guess his usual black outfit helps.
I captured a few moments of him immersed in his black and white world, as still as his drawings.
