Brian Daniels hangs a painting, titled Oscar the Ostrich, by a mystery artist in the Community Gallery for an "incognito" exhibition and sale raising funds for a new aviary at Orokonui Ecosanctuary and other charity projects.
Rotary Dunedin is celebrating its 100th anniversary with the event, which will have artwork from well-known artists, public figures and community members such as artist Ron Esplin, Dunedin Mayor Jules Radich and photographer Michael Sutton.
Mr Daniels said the difference with this exhibition was buyers would not be told who the creator of each piece was until the purchase was final.

Each painting would cost $150, and some could be worth more than 10 times that, Mr Daniels said.
More than 100 paintings would be up for grabs on the night, and there would be something for everyone, he said.
The event begins at 5.30pm on November 10, at the Dunedin City Council Community Gallery. Those interested are invited to look at the available art before sale night.
