Avid painter Charles's watercolour of Mount Athos in Greece has been reproduced into 100 lithographs, which are now up for grabs for £2,950 each.
The King, who is estimated to have sold more than £2 million of lithographs through the shop, modestly signed the painting 'Charles 2022' – although shop staff tell me he autographed them after ascending to the throne.
In fact, there was thought then to print some works of the then Prince as postcards, however, the idea did not proceed.
