Now You Can Lick Harry's Back And Not Get Arrested!

He's on a stamp, calm down sergeant!

Now you can go all old school and send letters (from the UK only of course) or simply collect the stamps to admire them. Or you know, just lick them.

Prince Charles and his two sons feature in a triple portrait in a set of Royal Mail stamps to mark his 70th birthday.

Charles, along with Prince William and Prince Harry, was photographed during the July celebrations at Buckingham Palace that marked the RAF's 100th anniversary.

The Duke of Cambridge served as an RAF search and rescue helicopter pilot for a number of years, while the Duke of Sussex is honorary Air Commandant of RAF Honington.

If you're a fan of Harry and Wills, there's also a super-cute old shot of them at the polo to admire... we mean, stick on the wall... we mean, on a letter.

One of the set of stamps shows an image of Charles hugging wife Camilla -- which was used for a 2015 Christmas card -- while the last is a photograph of the prince by himself.

The six stamps are available to pre-order from the Royal Mail website and go on general sale from Thursday.

Photographer Chris Jackson shared the group photo on his Instagram account, telling followers he took the shot and joking, "I expect you all to send your Christmas presents only using this stamp!"
