Focusing on architecture, art and design, each of Phaidon's Wallpaper City Guides is illustrated with more than 50 color photographs and protected by Pantone covers. These pocket-sized travel bibles point you toward a city's hippest nightlife, buzziest hotels, coolest retail, most influential art galleries and cultural spaces, and the best in local design and contemporary architecture. More than 100 destinations are available, from Atlanta to Zurich. Ten volumes are also available in French.

Also distributed for iPhone and iPad, Wallpaper City Guides apps are more portable and interactive than the book versions, with extra features such as photo galleries and in-app web browsing. Tap the screen to call a restaurant to book a table, locate it on our map, and use GPS to discover where to go for a drink nearby.

Why the publisher would bother to print the books in French but neglect to make the apps available for Android is not explained.

Wallpaper City Guides are available in many book and travel stores, from Phaidon and at Amazon.
