Robert Hannaford has completed around 400 portraits over the span of his career.
Tim Flannery and artist Robert Hannaford discuss the creation of Tim's portrait.
Drawn from some of the many donations made to the Gallery's collection, the exhibition Portraits for Posterity pays homage both to the remarkable (and varied) group of Australians who are portrayed in the portraits and the generosity of the many donors who have presented them to the Gallery.
