Vintage Levi's Tan Leisure Wear Polyester Slacks

Vintage Levi's Leisure Wear Polyester Slacks. Made in U.S.A. of 100% polyester. Gently used. There is a small black mark right above the button on the waist band along the seam line. Manufacturing tag is still crisp leading me to believe that these slacks have had little wear or laundering. No snags, holes or stains. Photos are an important part of the description. Probably a 1970's item. Size on tag W42 L30
