With his arms outstretched and his eyes fixed on where he is going, the future king is striding ahead in the picture taken during a visit with his proud parents to the Sensational Butterflies outdoor exhibition at London’s Natural History Museum.
The youngster will celebrate his first birthday tomorrow, and the Duke and Duchess of Cambridge are expected to hold a birthday party for him at their Kensington Palace apartment with close family and friends.
In the picture taken a few weeks ago, George is dressed in a pair of dungaree shorts from French label Petit Bateau, over a polo shirt-style top. Kate is wearing a green 1930s-inspired Budding Heart Silk Tea dress, by British brand Suzannah, (£475).
The Prince’s blond hair has been swept across his head to create a stylish look and he has what his uncle Prince Harry has described as big chubby cheeks and the appearance of a “young Winston Churchill”.
Press Association photographer John Stillwell took the picture and has photographed some of the key stages in the Prince’s life, from his first public appearance the day after he was born to his christening last October.
Mr Stillwell said: “Prince George was very lively and very sure of himself and confident — a very determined young boy.”
The birth of George Alexander Louis, known as His Royal Highness Prince George of Cambridge, was a global event, with the world’s media camped for days outside the private maternity Lindo Wing of St Mary’s Hospital in London.
