Auctioneer Scott Millen said that he was excited to offer such a significant painting and estimated it would sell for between $50,000 and $70,000.

``The 1822 signed and dated oil painting is an homage to 19th century artist Richard Wilson, a man whose work Glover greatly admired - probably of a scene in Italy,'' Mr Millen said.

``At some point in its history, Glover actually owned Wilson's painting - it now hangs in the Victoria and Albert Museum, in London.

``We've uncovered many Glovers over the years and there seem to be takers whenever we have them, but we've had nothing as significant as this piece before.''

Mr Millen said that the oil painting was just one of five Glovers in today's antique, art and collectables auction.

``We also have a watercolour - probably the largest Glover watercolour ever offered in Australia - and we're reasonably confident that it's still in its original frame,'' he said.

``The small works include two sepia ink on paper, most definitely leaves from Glover's sketch books and a double-sided work.

A range of items will be auctioned today from 9am.
