Bond trader-turned-artist James Wilkinson will be selling several celebrity portraits at a swanky bash held by auctioneers Cooper Owen at Madame Tussauds waxwork museum on Wednesday.

Wilkinson, who went to art school before embarking on a decade-long spell as a bond trader with the likes of Merrill Lynch, PaineWebber and Deutsche Bank, subsequently swapped his squawkbox for the paintbrushes again.
