70s Mens Pants Vintage 32 Waist 35 Inseam Chinos

Vintage 70s Mens Pants by JCPenney Coordiated Sportswear Ltd - tag says dry clean but I washed in cold water without issue. Zipper with hook and button closures. Feels like a cotton/polyester blend to me. No materials or size tag. Compare measurements to pants you own. WAIST 32" (tag says 34 but these have shrunk, normal for cotton) Outside Seam LENGTH 45" Inseam 35.5". (tag says 37 so this is hemmed length, no material to lengthen) Thigh 24" around, ankle 22" around Flaws: light marks scattered, see closeup photos, most obvious mark is at one knee
