The Collection wallpaper

The Collection is the place to go for your statement nursery wallpaper. All you need is one drop showing this impertinently scarlet traditional British phone-box: add a few other red accents in the shape of cushions or a rug, and your job is done.

If you prefer something more subtle, how about the park scene ('Parc'), below? I kind of like how it looks as if you let your child draw on the walls, but they did it really, really well.

For those who don't want to get too bold, there are also friezes, allowing you to bring a hint of the Collection's artistry to your house, without overwhelming the whole room.
