The original clover became the logo of Adidas from 1972, when all the products of Adidas used this logo. Clover is shaped like a three-dimensional plane of the earth, much like a map of the world, symbolizing that three stripes extend to the whole world. However, since 1996, the clover logo has been specially used for classic original products. The classic series is based on the best products in Adidas' history, and is re-released after slightly modifying its fabric and style. The whole series is fashionable, and the products include shoes, clothes, bags and other accessories.
