The children of Sussex have been thanked by the Duke and Duchess of Cambridge for their congratulations cards celebrating the birth of Prince George.

In July The Argus sent a congratulations card to Buckingham Palace after running Royal Baby Competition in the paper.

A drawing by the winner, Brook Barlow, was chosen by our readers and was mounted on the card sent to the Royal couple.

The card reads: “The Duke and Duchess of Cambridge thank the children of Sussex for the wonderful card sent on the occasion of the birth of their son, Prince George.

“Their Royal Highnesses have been overwhelmed by all the wonderful messages they have received and send you their warmest thanks and best wishes.”

Hundreds of entries for our Royal Baby Competition flooded into The Argus newsroom – and Brook Barlow’s drawing was selected by The Argus’ readers from more than 200 entries.

The Argus ran a competition in conjunction with Warden Park School to find the best drawing to go on the front of a card that was sent to Buckingham Palace.

Brook’s father, Paul Barlow, said: “I’m absolutely thrilled for him.

“You always enter these things but you never expect to win them.

“We had a look through and there was a good selection of really good entries so I’m delighted Brook’s has been picked.

“He’s got a bit of a wild imagination, so he just threw lots of ideas together into the picture.

“There’s lots of elements of how he sees Brighton. There’s some seagulls, the Marina, the wheel and all sorts of different bits and pieces.

“My 12-year-old daughter, Tiani, also entered the competition and she will be absolutely gutted I’m sure.”

Brook’s mother, Jo Barlow, 39, added: “I think it’s fantastic. He did his own thing, and because he’s only seven he went a bit mad with his drawing of the world.

“Originally he wanted the tagline to read ‘Welcome to Our Planet’, but we managed to persuade him that World was more appropriate.

“He absolutely loves drawing and writing.

“He’s getting there with it and he’s got a bit of flair so hopefully one day we’ll make an artist of him.”
