It's always interesting, I think, to get a peek behind the curtain of a successful logo and see some of the other possibilities that were being considered (or at least thrown out there in the brainstorming sessions).

I will be including some of my early drafts and concepts from time to time and when I do, I'll tag them accordingly for those who are interested in seeing some of the work and concepts that flavoured the final piece.
