Adidas 1963 Santiago ball
Adidas launched this model in 1963 as a reminder in 1962 Chile World Cup. In fact it is one of the first ball launched by Adidas. Available in collectibles section.
The Adidas Santiago was composed of long and round octagons as you can see in the photos. This model was made of genuine leather.
As you can see on the picture below, this model was already inflated by a current bladder.
In the 90's Adidas launched a reedition of the Santiago model. The photo below belongs to a replica of this nice ball.
The following images belong to authentic models of that time with a very similar sewing to Adidas Santiago.
