Happy Birthday Mr. Men: How To Draw The Characters

To celebrate the 40th Anniversary of Mr. Men, we've got a masterclass from creator, Roger Hargreaves' son, Adam so your little ones (and you!) can have a go at drawing the famous characters.

It was back in 1971 when the first character, Mr. Tickle, was created, after a then six-year-old Adam asked his dad, 'what does a tickle look like?'

Doodling a round, orange figure with long, bendy arms, dad Roger created the first character in the collection which is still loved by children of all ages today.

Check out the videos and have a go drawing Mr.Tickle and Little Miss Naughty - let us know how you get on!
