The official coronation portrait of Britain’s King Charles was made public on Tuesday, two years after he was crowned, in a tradition dating back more than 400 years to a time when such a painting often became the defining image of a monarch.

On Tuesday, May 6—exactly two years after his coronation ceremony—King Charles and his wife, Queen Camilla, were on hand in the Central Hall at The National Gallery in London to personally unveil the long-awaited portraits.

The portraits of King Charles III and Queen Camilla will be displayed in the National Gallery for one month before they are removed to their permanent home at Buckingham Palace. King Charles’ portrait was painted by Peter Kuhfeld, while the queen consort selected Paul Benney, respectively.
