A series of 18 photographs, taken by Mr Kwek Leng Joo, the managing director of City Developments Limited (CDL), a listed international property and hotel conglomerate, will be put on for sale by the co-organisers of the annual ChildAid concert, The Business Times and The Straits Times.

The photographs of rare and unique flowers were donated by Mr Kwek to ChildAid, a charity concert in aid of two funds to help students from low-income homes.

A Singapore Press Holdings spokesman said on Monday morning that the photo artworks were among the collection of 31 photographs which were exhibited as part of the "Flora Exotica" photo exhibition at the recent Singapore Gardens Festival, at the invitation of the National Parks Board.

The ChildAid concert, which will be held on Dec 7 and 8 at the Grand Theatre at Marina Bay Sands, aims to raise funds for The Straits Times School Pocket Money Fund and The Business Times Budding Artists Fund.

The Business Times celebrates its 36th anniversary today, while The Straits Times School Pocket Money Fund celebrates its 12th birthday.

All the 18 framed photo artworks will be displayed at a private exhibition at The Arts House at The Old Parliament, from Oct 14 to 18.

The prices of the photographs range from $20,000 to $50,000. The Business Times, the presenter of the photo exhibition, hopes to raise at least $500,000 from the sale of Mr Kwek's photo works.
