Levis Strauss made the first "blue jeans" in 1873, denim work pants that had metal rivets placed strategically at the strain points. The most collected variety of Levis is the 501 jean, or the earlier 501xx, which has seen around 20 versions in its 120+ year history.  Other "lots" of jeans such as the 502, 503, 505 and denim jackets are also popular among collectors and vintage clothing hunters.  Check out vintage Chuck Taylor and vintage Jack Purcell Converse shoes.
