The Henry Cooper theory is a great one but a little wide of the mark The name and design are inspired by three things, namely:
1) The colours and scent are taken from Faberge's Brut classic
2) The image is that of the Greek giant, Prometheus (albeit Sarah has worked her magic). Sarah's a classics fan and we both enjoy most of the Aliens franchise. We had thought to use a drawing of one of the Engineers but when Sarah started on Prometheus we were swayed by that
3) The name was inspired by a favourite brewery of mine, Bristol based Left Handed Giant (really, you should try their beer).
Hope that helps. Pre-order opens at 1200hrs (GMT), Friday 2nd August.
