For many people, Levi's (Levi's) is the source of all cowboys. The important design elements of jeans, which are indigo jeans denim, the back side of the waist, the curved line on the back of the trousers, the rivets and the unique red flag, all originate from the creation of Levi's (Levi's) jeans.

Levi's (Levi's) can not meet the requirement of single R red flag. In view of the relevant provisions of the international trademark, the red flag only marked "R" on the beginning, followed by the word "Levi's" (Levi's), which has been retained so far. And the original symbol of R is only one of every 1000 Levi's (Levi's) jeans in the world, so as to maintain Levi's's (Levi's) red flag as an important position of registered trademark. So when you find Levi's jeans with R logo, it's not like collecting brains, because the probability of 1/1000 is not available in the global market.
