Fans have been left puzzled by a painting in the National Gallery from the 17th century, which appears to show a boy wearing Nike shoes.
A mum and daughter spotted what appears to be proof of time travel on the Portrait of a Boy, painted by Dutch Master Ferdinand Bol.
It shows an eight-year-old boy standing in front of a chair next to a table with a red cloth on it, while holding a goblet, which is resting on the table.
