The clover (adidas Originals) has become the logo of Adidas since 1972, when all Adidas products used this logo. The shape of the clover is like the three-dimensional expansion of the earth, much like a world map, symbolizing the three stripes extending to the whole world. But starting in 1996, the clover logo has been exclusively used on classic series Original products. The classic series is based on the best products in Adidas history and is re-released with slightly modified fabrics and styles. The entire series is more fashionable, with products including shoes, clothing, bags and other accessories.
