This is the album cover, the designer were Tappin & Gofto

Tappin & Gofto: "The main source of inspiration for the artwork was effectively discovered
 through conversation with the band. They're very passionate about their 
artwork and always have an idea for the kind of thing they want. It's kind
 of down to us to help try and bring this into reality and work through ideas 
with them until a direction is agreed upon collectively. We worked with the band on and off for a period of 
approximately five months before we reached the final direction for the
 artwork. When we had agreed the final art direction it then became more about how
 we got the very best out of the idea and about the details of the design for the
 album cover and associated artwork parts like the booklet, the label, the 
typography, etc. It was great, because even at that stage the band really like
to be involved, you really have to work thoroughly though all your ideas."
