A row has begun in the art world over the authenticity of works which their seller says are by Co Antrim-born man Basil Blackshaw - described as one of Ireland's finest artists. Viewers of the BBC art programme Fake or Fortune? are often on the edge of their seat as host Fiona Bruce and her team try to establish the authenticity of paintings. Now art lovers in Northern Ireland have their own Fake or Fortune? mystery after the late artist's estate issued an alert over some of the Blackshaws on sale. The estate of Blackshaw, who died in 2016, warned that there were a "huge amount of paintings purporting to be painted by Basil Blackshaw".
