This book is an invitation to reexamine Brazilian history through postcards that show how the people of Brazil transformed their nation in the course of the 20th century. In our modern era, with its lifestyle-enhancing technological innovations, the images presented here invite us to travel back in time and witness the changes Brazil has gone through over the past hundred years. The country's most important cities are depicted in these postcards, which we have brought together to celebrate one century of Siemens in Brazil
