Volunteers were yesterday in a race against time to rescue scores of protest-inspired artworks ahead of a possible police clearance operation in the main Occupy site outside the government headquarters in Admiralty. Together with works retrieved from the Mong Kok site last week, volunteers for Umbrella Movement Visual Archives and Research Collective have collected around 100 works for future research. Clarisse Yeung of the collective said about 50 volunteers in 10 teams had arrived in Admiralty just before protesters and police clashed in Lung Wo Road early yesterday morning. "Our volunteers acted swiftly to retrieve the works. We had help from protesters on the site too. It went smoothly," said Yeung. But it was not all peaceful as some volunteers were accused by radical protesters of wasting time on art instead of taking to the front line to battle the police. Works collected yesterday included banners, sculptures, signage and drawings created over the past two months. They included the iconic sign kwong ming lui lok , which formed part of the main barricade outside the Red Cross headquarters in Harcourt Road. The four-character expression means upright and honourable. It was used by the police to describe their law enforcement tactics. But it became a sarcastic phrase after the incident in which seven plain-clothes policemen allegedly beat Civic Party member Ken Tsang Kin-chiu, who was also a pan-democrat member of the 1,200-strong election committee which picked Leung Chun-ying as chief executive in 2012. The volunteers also saved a road sign reading "Road To Democracy", which was erected outside the government headquarters, and a cardboard sculpture in the form of a man covered with post-its. They also took away protest banners removed by the police. However, a patchwork canopy made of umbrella material which was hung on a bridge across Harcourt Road remains in place as the creators from Baptist University have yet to decide its fate. Yeung said the artist nicknamed Milk had taken back his Umbrella Man sculpture for repair.

They collected makeshift objects including shields made of soft padding and empty water bottles and cutouts depicting President Xi Jinping holding an umbrella. But she said they could not save everything before the bailiffs moved in to clear the sites. The retrieved works are being kept in a "safe place" for archival purposes. Wen said there had been global interest in the art, but volunteers hoped to keep them in Hong Kong for future research purposes. Meanwhile, an exhibition showcasing the public's participation in street art during the protests is being held at the Jockey Club Creative Arts Centre in Shek Kip Mei. The show runs until December 31.
