Royal Mail’s Special Stamp programme kicks off 2014 with an issue that celebrates more than 60 years of Classic Children’s TV.

A dozen of the most popular characters from children’s television are included in the set.

The full line-up features Andy Pandy, Ivor the Engine, Dougal - from The Magic Roundabout, Windy Miller - from Camberwick Green, Mr Benn, Great Uncle Bulgaria - from The Wombles, Bagpuss, Paddington Bear, Postman Pat, Bob the Builder, Peppa Pig and Shaun the Sheep.

This year will mark the 40th anniversary of Bagpuss first appearing on TV. The saggy cloth cat is continually cited as one of the most favourite British children’s TV character of all time.

The year also marks the 50th anniversary of The Magic Roundabout. The prolific British animator Ivor Wood created Dougal, one of the show’s most popular characters, who also ranks highly in people’s affections.

Wood also went on to animate Paddington Bear and Postman Pat for TV, two more of the most popular animated characters.
