The Chocolate Surpresa was a brand of chocolate made by Nestlé in Brazil.
It was introduced on 1983 and was popular in the 1980s and the early 1990s, but its popularity declined and it ceased to be produced in the year of 2000.The chocolate itself was a common black milky bar, flat and thin. But what really made it achieve so much success was that each of them would come with a figure made on a thin cardboard paper with a picture of an animal on it.Nestlé, understanding the potential of the pictures, started making themed albums where the pictures would be glued. To obtain the albums, kids in Brazil would buy three or four bars of Chocolate Surpresa and send the packaging in a letter to Nestle. A few days later the album would arrive at home. [Wikipedia]
