A few of Banksy's pieces can sometimes seem to some to be a little on the edgy side. Not many of his pieces are more applicable to this description than in Golf Sale, in which he recreates the scene of the 1989 Tiananmen Square protests in China, during which an unarmed Chinese man known only as "Tank Man" and "The Unknown Rebel" stood firm, alone, in front of a long line of Chinese tanks, bringing the whole line to a halt, as a part of a protest against government corruption that led to the deaths of hundreds of innocent protestors, murdered by the Chinese government.
Even now, all photographs and documentation of the protests and the massacre are banned in China and blocked by Chinese internet service providers.
In fact, the event was so successfully redacted from the public eye that many present day Chinese people are completely oblivious to the events that took place that day.
When shown photgraphs of this particular incident, most modern Chinese people assume that it is some sort of performance art piece rather than a legendary historical one-man stand against oppression during one of the worst periods of atrocities against their own people that China has ever seen.
It is highly likely that The Unknown Rebel doesn't even realise that he became an international icon for his actions that day, or was even photographed, let alone published in just about every newspaper in the civilised world outside his home coutry's borders.
In the Banksy's stencil graffiti piece Golf Sale, as seen on this Golf Sale sweatshirt, the man's carrier bag of suspected shopping has been replaced with a red sign that reads "Golf Sale".
