The Cutest Prince George Portrait Yet – and the Secret to How He Got So Tall! See 4 Generations of Royal Heirs in Amazing New Photo
It’s the future King and the reigning Queen – or as they’re known to each other, George and Gan-Gan.
Holding onto the right hand of his dad Prince William, 2-year-old Prince George – standing tall on a stack of foam blocks – shows off a huge smile and the famous Cambridge cheeks in a shot taken last summer in the White Drawing Room at Buckingham Palace and released on Tuesday.
Photographed by Ranald Mackechnie, it is the first time George has appeared on a British stamp and was released in celebration of the Queen’s 90th birthday on April 21.
(And yes, he’s wearing his signature knee socks – the very same ones available in PEOPLE Shop!)
The little royal had a little help to make sure he was roughly on the same “line” as the adults, with Mackechnie using high-density foam blocks to lift him into the frame.
The Royal Mail released the four first-class stamps (cost: 54 pence each, or 78 cents) on a single sheet, with perforations around the faces of the four royals.
There are also six special stamps that celebrate Queen’s birthday. Three focus on Her Majesty s family life, including one of her with her children and, for the first time a stamp with her father, King George VI.

The other three mark the Queen’s official role, showing her as Head of State for the opening of Parliament; as Head of the Commonwealth, where she is shown with the late South African president Nelson Mandela; and on a state visit to New Zealand.
The stamps are available to pre-order starting on April 20 at and available to buy from 8,000 Post Offices around the U.K. beginning on April 21.
