The photo was featured in the BBC documentary Prince, Son and Heir: Charles at 70.
It was made in celebration of the Prince of Wales upcoming 70th birthday - on November 14.
Containing more gems than the tower of London, the show also gave a rare insight to one of the most controversial things to happen this year - Thomas Markle dropping out of his daughter's royal wedding.
Prince Harry broke his silence and spoke about his father's reaction to being asked to walk Meghan Markle down the aisle on their wedding day.
"I asked him to and I think he knew it was coming and he immediately said, ‘Yes, of course, I’ll do whatever Megan needs and I’m here to support you,'" Harry confessed.
"For him that's a fantastic opportunity to step up and be that support, and you know he’s our father so of course he’s gonna be there for us."
He then added he was so "grateful!"
Duchess Camilla described the gesture as "rather touching".
"It's the things he does behind the scenes that people don't know about."
The BBC One documentary also shed light on what a wonderful grandfather Prince Charles is.
"He will get down on his knees and crawl about with them for hours, you know making funny noises and laughing and my grandchildren adore him, absolutely adore him," Duchess Camilla revealed.
