Look out for these colourful characters from children's books in Hemel Hempstead to mark World Book Day.
To mark this World Book Day, and spread some community cheer, Yarn Bomb Hemel Hempstead has been busy creating the knitted postbox toppers which will create a special trail.
And the free, interactive trail will be supporting local charity DESC - The Dacorum Education Support Center.
And if that wasn't enough, there's also a chance to get your hands on a £50 voucher.
Painted pebbles have also been left around many of the post boxes thanks to Pat Jackman and local community group Hemel Rocks.
And Hiddenbooks Hemel has also placed several books in plastic sleeves around the area for children to discover.
The trail is set to launch on Sunday (February 27) and will run until March 19.
