An odd thing I just noted. Here are the Australian and one of the UK covers for the late Christopher Hitchens' big book of essays, Arguably.
It's the same photo, but for no readily apparent reason, flipped over. This means that somebody had to go in and fix the book spines in the flipped image (which would be the UK version at bottom), though it hasn't been done quite perfectly. The Vanity Fair Portraits on the floor has had its spine fixed, but not the front cover (original on left, retouched on right--click for bigger).
And the books on the shelves have been changed, too: the books in the box have been flipped around, but the book immediately above them has had its spine flipped, but not its cover--peer closely, and you'll see the mismatch.
So I find myself wondering why this was done at all? Why flip such a tricky photo when the original seems fine? Why make so much pointless work for a graphic designer? And, more importantly, why have I then wasted a whole heap of time peering at this and pointing it out?
