Mr Men and Little Miss to feature on new set of stamps - are you happy or grumpy about it?

Mr Bump, Mr Tickle, Little Miss Sunshine, and of course Mr Happy and Mr Grumpy, feature on the 10 stamps - which mark the 45th anniversary of the books by RogerHargreaves.

He created the first book after his son Adam asked him what a tickle looked like, inspiring a copywriter to visualise a small orange man with long arms.

Since 1971, 50 Mr Men and 36 Little Miss books have been published - and Adam took over from his father following his death in 1988.

He 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."

Philip Parker, of Royal Mail, said: "The Mr Men and Little Miss characters are a worldwide phenomenon.

"People identify with the different character traits, and we hope these stamps will brighten up the sending and receiving of mail."
