'The first thing I ever picked up to read for pleasure was The Beano.' – David Walliams

Craig Graham and Mike Stirling were both born in Kirkcaldy, Fife, in the same vintage year when Dennis became the cover star of Beano. Ever since, they've been training to becomes the Brains Behind Beano Books (which is mostly making cool stuff for kids from words and funny pictures). They've both been Beano Editors, but now Craig is Managing Editor and Mike is Editorial Director (ooh, fancy!) at Beano Studios.
