Artist Joanne Anderson’s unique tribute to the royal family shows Prince William, Kate Middleton, Prince George and Princess Charlotte in a way that you’ve never seen them before -- as life-sized balloons.

The artist spent 16 hours blowing up the balloons with helium and tying them together to create her royal family tribute, the Mirror reported Wednesday. Anderson, 42, said that she had the idea to create balloons of the young royal family while the Duchess of Cambridge was still pregnant.

"I think they're a really nice memento," she added. "People do paintings and make china but I don't think anyone's ever created them out of balloons.”

Anderson used peach-colored balloons for Kate Middleton’s dress, edged with daisy-like balloon flowers since she wanted Kate’s balloon figure to look bright and warm, just like the Duchess’ personality. The Prince William and Prince George figures are decked out in blue, similar to what the father and son wore when they first visited Princess Charlotte. Anderson said William and George looked so iconic in the outfits that she knew immediately she would dress her balloon figures the same way.

Anderson, otherwise known as “Betty Balloon,” started doing balloon art four years ago. The Longridge News reported that it all began when her daughter D’arcy asked if she could invite some friends around for a tea party. She was thinking of ways to entertain the children and her friend taught her how to make a balloon dog. From then on, she was hooked and started doing children’s parties along with creating balloon caricatures of people.

Her creations include Michael Jackson, Elvis Presley, the Sex Pistols, Dennis the Menace and others.
