You may recognise the top middle picture from my pic the other day! These pictures are near where we are staying.
Venice by Jiro Tanaguchi is a book of watercolours of Venice. It is billed as a "graphic novel" but I wouldn't really call it a story. It's more of an art book with narrative aspects.
Flipping through trying to work out which bits we'd seen was fun (e.g. my friend: "that's the bridge where you started complaining your feet hurt").
