This is the original photo on which the book cover is based. It didn’t quite work, there was too much clutter on the front cover, so we mirror-imaged (reversed) it so that the actual book cover is back to front (stand by the canal at the lock and see for yourself!). But the writing on the notice on the bridge came out back to front, so we had to do clever things with Photoshop. There are 71 colour photographs in the book.
