Another 'rough' that I tried out on National Geographic Kids' magazine, after they asked me to come up with something, in 2008. I suppose I was thinking of the Look and Learn or World of Wonder approach, hence the fancy colouring (by me). Anyway, it was not to be- in fact I never heard back about this, so I guess it wasn't good enough. Nor my proposed follow ups, Mission Apollo, the Polynesians, Francis Drake, Magellan, etc etc. And don't try reading the text, it's just there to look 'finished'!
Thinking about it, I shouldn't have been surprised I got nowhere with this, the editor in charge had been at Marvel UK previously! I should have known!!
