There's no need to rush in Porto, in fact the steep hills make it ill advised to even try. This is a city made for wandering - down through the winding streets of the Baixa district to the river; through Casa de Serralves, an Art Deco mansion and contemporary art gallery. Small and tightly focused, our guides are concise city tours in a handy fold-out format that slips neatly into an intrepid traveler's pocket. Our aim is to introduce readers to new places as well as re-evaluating familiar ones, and we are as keen to find a new way to see the Louvre as we are to discover an untouched 1950s café. Informed by on-the-ground research, our one-sheet guides and maps uncover what makes a city special. They are written and researched in-house, and an illustrator who has been specially chosen for the subject designs each one. Whether it's an excursion into the greener areas of London (more numerous than you might think), Paris's beatnik bookshops, the otherworldly landscape just outside Reykjavik, or the watering holes of Brooklyn, we highlight what makes a place distinctive with our specialist knowledge and illustrations with vintage charm. In A6 format, the guides fit easily into a pocket and then expand out to A3 or A2 to display the attractions of each city. Each fine-quality sheet is litho-printed in England on 100% recycled stock.
