Abosch's explanation of how the sale came about suggests wine might have had something to do with the transaction.

Abosch, who is based in France and Ireland, was having dinner with an unnamed European businessman at his home when his guest saw the photograph hanging on the wall, The Sunday Times in London reported.

Abosch had photographed the potato in 2010, after it was delivered to his home in a batch of organic vegetables.

"We had two glasses of wine and he [the businessman] said, 'I really like that.' Two more glasses of wine and he said: 'I really want that,' " Abosch said
