It is a stunning sketch which has prompted much discussion about the artistic talents of Britain's future king.
And so impressive is Prince George's drawing of a kingfisher that it featured in this month's edition of Country Life, guest-edited by his father.
However, eagle-eyed observers have spotted something familiar about the 13-year-old's artwork.
For a remarkably similar bird – right down to its distinctive feathers and angled stance – appeared in a YouTube drawing tutorial seven years ago.
And having assessed George's efforts, the artist, Matt Fussell, was very impressed indeed.
He told the Daily Mail: 'Prince George did a fantastic job on his kingfisher drawing. It's a beautiful piece of art and he should be incredibly proud.
'While I can't say for certain whether he used my lesson, the similarities are certainly exciting to see.'
He added that he would be 'thrilled' if the royal had followed his tutorial.

It is not known if George took inspiration from the video or whether the similarities are a coincidence.
'Then in June I was sent this picture George had done. I looked at it and I knew it was going to be a big deal.'
