This J.M.W. Turner self-portrait is such a famous image of the painter it even adorns the British £20 note - but now one expert says it is by someone else.

James Hamilton used the pages of the Turner Society newsletter to argue it is more likely the work of his contemporary John Opie.

He believes it was "lumped in" with the thousands of paintings and sketches collected in the Turner Bequest following the artist's death which eventually saw his work left to the nation and split between London's National Gallery and the Tate.

Hamilton told the Guardian newspaper people had just assumed it was a self-portrait despite a lack of evidence, adding: "Nothing would please me more than for the Tate to show us that this is a self-portrait … But they haven’t."

A spokesperson for Tate said it would "always welcome new ideas about Turner’s life and new interpretations of his work" and looked "forward to exploring James Hamilton’s research further".

Museum director Melissa Chiu said: "Acquisitions made throughout our 50th-anniversary year, including 50th-anniversary gifts, bolster long-standing areas of focus within the national collection, notably photography, and introduce works by important working artists including Thomas Houseago, Marilyn Minter and Ezra Stoller to its holdings".
