A new series of special Royal Mail stamps features 12 of the best-loved British children's TV characters from the past 60 years, from Andy Pandy and Bagpuss to Peppa Pig and Bob the Builder.

The stamps, designed by London-based design agency Interabang, represent each decade of children's TV since the 1950s, and a variety of animation techniques, from hand-drawn to stop-motion. They have a sticker-like appearance, with the characters breaking out of the stamp borders.

Among the stars of the series are Bagpuss, the famous pink-striped cat that celebrates its 40th anniversary this year, as well as Dougal from classic kid's show The Magic Roundabout, which is celebrating its 50th anniversary.

"For over 60 years, Britain's children's TV characters have brought cheer to generations of viewers," said Royal Mail Stamps' Andrew Hammond. "More importantly it has presented us with a cast of characters that, like the memories of the programmes themselves, remain with us throughout our lives. It feels appropriate to celebrate all of these unforgettable characters on a set of very special stamps."
