 A popular piece of street art destroyed by Hong Kong authorities has been remade and is expected to fetch more than HK$1.5 million (US$192,000) at a Sotheby's auction next week.
It comes as experts say the demand for "cutting edge" art is growing across the Asian market with new, younger collectors emerging.
The ceramic mosaic of 1970s American cartoon character Hong Kong Phooey -- a mask-wearing dog who is an expert in kung fu -- was created by high-profile French street artist Invader.
It first went up on a wall in a quiet street of Hong Kong's upmarket Happy Valley neighbourhood last January.
But the artwork, which measures 1.3 metres x 2.1 metres (52 inches x 82 inches), was taken down within weeks by Hong Kong authorities, sparking outrage from residents.
Now the French artist has recreated the mosaic -- which has the character performing his signature flying kick -- and it is slated to be the highlight of Tuesday's auction.
It will be sold alongside the first ever work to be auctioned in Hong Kong by British artist Tracey Emin -- a turquoise neon sign that reads "Trust Me", expected to fetch up to HK$350,000.
"There are some very important collectors acquiring Monet and Van Gogh, but there's also a deep pool of new collectors trying to acquire more cutting edge pieces," Isaure de Viel Castel, Sotheby's head of mid-season sales for contemporary and modern fine arts, told AFP.
Artists such as Invader are responding to this challenge by making replicas of their works so collectors can take them home, she said.
"We're reaching out to new collectors here, people in their 30s or 40s who are very international."
Hong Kong has emerged as one of the world's major auction hubs in art and wine thanks to cash-rich mainland Chinese buyers with an appetite for luxury items.
The government is also developing a new art and culture district on the Kowloon waterfront where contemporary art museum "M+" is expected to boast a world-class collection.
