Griffin & Sabine was published in 1991. I have owned the book for many years but was reminded of it by another Nick Bantock book that was linked in to Books You Loved.
I'm so glad I read it again. What a gem of a book. It's more an artwork than just a book. The story is mysterious – I won't discuss it here in case you have never read the book.
The book has a tactile quality to it – on many pages you have to open an envelope and take out a letter to read it.
Nick Bantock is clearly a major talent. If you haven't got this book, I recommend it to you.
