I love the way that even the Penguin Classics branding uses cut-up bits of old Penguin designs: a 1970s Modern Classics logo, a 1990s 'Penguin Classics' bit of type, and the author's name from the newest 2000s Classics type.
UPDATE: Designer Stefanie Posavec write to say that she provided the cut-up Penguin bits, and the original collage (see below) was altered by Harland Miller.
Also, if you ever see that film of 'The Black Cat', the poster of which decorates the wall in that collage, you're in for 65 minutes of serious bonkersness.
UPDATE: Super-star JonathanM of the Bookseller Crow points out what I was too stupid to realise, which is that this is a Poe-ised modification of Richard Hamilton's 'Just What Is It that Makes
Today's Homes So Different, So Appealing?'.
