The story
Product history
In 1971 the German Football Association granted Hasana exclusive rights for children's sports- and leisure underwear sporting the logo of each of the 16 teams competing in Bundesliga, Germany's professional football league.
This later led to similar exclusive rights to use the logo of 1974 FIFA World Cup on textiles.
