The finest book cover illustration I’ve seen for this slim, timeless, moving book, wrapping around the back cover and even into the back flyleaf.  Oddly, there is no mention of who designed the jacket.  The colours and lines are marvelous.

And that font!  ‘Ernest Hemingway’.  If you can tell me what it is, I will send you a bar of chocolate.
