Gifts given to royals when they were children, including the youngest Prince George, go on display today at Buckingham Palace.
Prince George celebrated his first year today, but can you guess who these young royals celebrating their first birthdays are?
As Prince George, third in line to the throne, celebrates his first birthday today, we take a look back at his first year.
Prince George is a "lively, confident and very determined young boy", a photographer who has captured the key stages of his lives has said.
The Prince has been photographed by the Press Association's John Stillwell with his arms outstretched and walking confidently in an official picture released ahead of his first birthday on Tuesday.
"Prince George was very lively and very sure of himself and confident - a very determined young boy," Stillwell said.
"When you have children yourself you don't realise they grow up in such a short space of time, it's always other people saying how big they've grown.
"So having seen him soon after he was born and at his christening three months later, he's now gone from a baby at his christening to a toddler, that's the biggest change.
"And who does he look like? I'd have to say his dad, William."
The first official birthday photograph of Prince George has been released ahead of his first birthday on Tuesday.

The Duke and Duchess of Cambridge are expected to hold a birthday party for him at their Kensington Palace apartment with just close family and friends.
Prince George may only be nine months old but his proud father, The Duke of Cambridge, would like to see him in the future experience the "wonders" of snorkelling and scuba diving.
The comments come as Prince William became president of the British Sub-Aqua Club (Bsac) governing body, the third generation of the monarchy to take the helm of president.
In a foreword for the magazine 'Scuba,' the Duke of Cambridge said he hopes his son Prince George will take up scuba diving,
Prince William said: "Just like my grandfather and my father, I am proud to say that I learnt to dive with Bsac, and share your passion for the sport and the underwater world.
"I hope that one day my son, George, will also experience the wonders that snorkelling and scuba diving have to offer."
