Beano comic. Unfortunately kids comics/magazines aren't what they used to be, and more often than not I try and steer my boys away from the trashy children's magazines on display in the supermarket as I feel most are a complete and utter waste of money, sucking the kids in with the free plasticy rubbish sellotaped to the front cover.
With this in mind, it was a complete joy to stumble upon 'Anorak' magazine -'the happy mag for kids'!
Analogue books - very cool shop!) but you can buy it online, or give a subscription to a child as a present perhaps? It's also worth checking their website, they even have a blog, bursting with fab ideas and illustrations - - you definitely don't have to be a kid to enjoy it!
