A painting created at the former home of Ring of Bright Water author and naturalist Gavin Maxwell could sell for £70,000, auctioneers have said.
Oxford-born artist Winifred Nicholson's Sea Treasures depicts a view from a window of Maxwell's property in Sandaig in the Highlands.
Bonhams will auction the painting on 9 March in London and estimate it could sell for between £50,000 and £70,000.
Maxwell's 1960 book told of his efforts to raise an otter rescued from Iraq.
The naturalist died of cancer in 1969.
