A 400-year-old gallery portrait appears to show a young boy wearing a pair of Nike trainers, it has been claimed.
The portrait by Dutch painter Ferdinand Bol, at the National Gallery, London, depicts a pensive-looking eight-year-old boy holding a goblet.
But amused tourists pointed out the boy appeared to be wearing a pair of Nike trainers.
Mother Fiona Foskett, 57, spotted the anomaly while visiting the London museum with her daughter 23-year-old daughter Holly.
Mrs Foskett, from the Isle of Wight, said the trainers ‘really stood out’ and joked that the boy was a ‘time traveller’.

She told The Sun: ‘I was looking at the painting and the trainers really stuck out to me. I said to my daughter, ‘Hold on, is he wearing a pair of Nike trainers?’
‘It had us in fits of laughter. He’s certainly a trendy-looking youngster.
‘Looking at the age, he must have got his hands on the first pair of Nike trainers ever made. Or is he actually a time traveller?’
The boy in the picture is said to be Frederick Sluysken – the second cousin of artist Bol’s wife and the son of a wealthy wine merchant.
A National Gallery spokesman said: ‘We are delighted that this picture has been such a hit with our visitors.
‘It resonated with followers when we put out a tweet asking people to see if they could spot a more “modern” detail by taking a closer look at the shoes of the eight-year-old boy in the portrait.’
