Photo taken from the wall at Franklin Centre at CUHK Campus in Shatin, Hong Kong. It is in protest against alleged bad labour conditions at the Coca-Cola plant.
One could argue that the copyright (moral right of droit au respect de l'intégrité de l'oeuvre) of the Pulitzer Prize winning photo by Eddie Adams is infringed.
