Levi's 501 made in the USA, dyed black, size W36. The color is well-preserved. Rare black denim made in the USA. It's a Circle R. The button back is 525, and the inner tag is a square tag, so I estimate it's from the late 80s. The back of the inner tag is faded and unreadable. This black denim is rarely seen, and the condition is good, so I think it's quite rare.
