Well from the left we have the UK hardback, UK paperback, US hardback and German editions of REVOLVER.
I love seeing the way one book gets a different look in each country it's published in. The big debate we had in the UK was whether to put a gun on the cover of the original HB. All sorts of issues to be considered, of course.
The final decision was no, but for the PB the answer has been yes, and the new look is pretty lovely. Interesting that both the US and German editions include a human element, even though you have to look fairly hard to see it.
