A piece of history is said to have been revealed after paint began to peel off a wall under a railway bridge in Mong Kok. It is hoped that graffiti of the late Tsang Tsou-choi - known as the "King of Kowloon" - is once more seeing the light of day.
A group called "When in Doubt" said members walking under a Boundary Street bridge found artwork by Tsang, who shot to fame after his death.
The graffiti - which can be seen on the Google Arts & Culture website - was covered with paint in 1997. The Leisure and Cultural Services Department said it will assess the discovery.
The "King" had said Kowloon City was given to his ancestors as a fief before it was ceded to Britain during the Qing dynasty. Dissatisfied with the government's occupation of "his land," Tsang began to file petitions in 1956 and paint graffiti around town to declare his sovereignty.
His graffiti was included in the exhibition of the M+ Museum "Hong Kong: Here and Beyond."
His works were auctioned after his death in 2007 at the age of 85. In 2009, his ink on wood print and a photograph of him in action with Lion Rock as backdrop sold for HK$212,500 in a Sotheby's auction.
