The latest family portrait of the British royal family featured a cheerful looking Prince George with his great grandmother Queen Elizabeth II, grandfather Prince Charles and father Prince William.

New photos of the 2-year-old royal toddler Prince George were taken for the special edition stamps to mark the queen’s 90th birthday. The family portrait was taken at Buckingham Palace’s White Drawing Room last summer, according to People magazine.

In the photo released on Tuesday, April 19, all four generations of the royal family wore big smiles as they faced the camera. Queen Elizabeth II, Prince Charles and Prince William were photographed sitting down, while Prince George stood on top of a stack of foam blocks beside his father so that he could be photographed near the same eye level as the queen.

The photos, taken by Ranald Mackechnie, will feature on the special stamps to celebrate the queen’s birthday. It would also mark the first time that Prince George featured on a stamp. Four first-class stamps, placed on a single sheet, have been released by Royal Mail, with perforations placed around the faces of all four royals.

The same photo was also released by Kensington Palace through its official Twitter account Wednesday.

Meanwhile, in an interview with Telegraph, photographer Mackenchnie recounted how Prince George was “absolutely charming” during the shoot. He commented that the young prince “was on good form” and that “everyone seemed to enjoy seeing him enjoy the day.”

Apart from the four stamps that featured Prince William, Prince Charles, Prince George and Queen Elizabeth II, the Royal Mail also released six other special stamps. Some of the stamps showed the Queen as a young mother, a few scenes from her family and royal life, as well as a stamp featuring her father, King George VI.

The special stamps are available for pre-order beginning April 20 through www.royalmail.com/hmq90. They can also be purchased from over 8,000 post offices, starting April 21.
