These Levi's Have A Unique Red Tab On The Pocket. It Simply Has An "R" On It. Here Is An Explanation For This Tab:
"You might come across a pair of Levis with just the trademark and write them off as a fake, however, they are intentionally designed with the almost blank tab. Since the tab is copied the world over, it requires extra-legal force from Levi’s and their right to market clothes with the tab. They, therefore, have to produce a certain percentage of Levi’s products with a plain Tab and just the trademark symbol. This shows that Levi’s owns trademark rights in the Tab itself, not just Levi’s wording."
