Old signs show us way to help charities

They're not exactly Banksy-level, but old bus-route signs that could be art to some - or at least conversation pieces - are up for auction.

Bus operator KMB will auction off 77 signs that are more than 20 years old, with the money going to its charity fund.

Most of the signs were used at the Shing Mun Tunnels bus interchange and Tai Po Industrial Estate bus terminus. Words and numbers on the signs were printed or written manually, KMB said. Starting prices range from HK$450 to HK$2,500 and bids can be submitted online to the KMB Shop until December 20.
