At least 1,000 paintings that the artist Damien Hirst said were “made in 2016” were created several years later, the Guardian can reveal.
...five sources familiar with the creation of the works, including some of the painters who put the dots to paper, told the Guardian many of them were mass-produced in 2018 and 2019.
Their accounts suggest at least 1,000 – and possibly several thousand – paintings in The Currency series were made during the two-year period. They were produced by dozens of painters hired at Hirst’s company Science Ltd at two studios, in Gloucestershire and London, in what one source described as a “Henry Ford production line”.
