Royal Mail have issued a special set of stamps today to celebrate 45 years of Mr. Men Little Miss! The collection features 10 characters: Mr. Happy; Little Miss Naughty; Mr. Bump; Little Miss Sunshine; Mr. Tickle; Mr. Grumpy; Little Miss Princess; Mr. Strong; Little Miss Christmas and Mr. Messy.

‘People identify with the different character traits, and we hope these stamps will brighten up sending and receiving mail.’ said Phillip Parker, at Royal Mail.

Core products include Mint Stamps (10 x 1st class stamps), first day cover, a presentation pack with bespoke artwork from Adam Hargreaves and his personal story with the brand and a retail stamp book.

Of the collaboration between two iconic British brands, Adam the son of creator Roger Hargreaves said: “I feel incredibly proud and I think my father would have been equally proud and really chuffed. It’s a real accolade for the Mr Men and Little Miss characters to be on a Royal Mail stamp.”

The stamps are available from from 20th October, and at 8000 Post Office branches in the UK.
