Levi's 502 Big E Deadstock. It's a waist chain model, so I believe it's from the later period of the Big E. The button back is 16. The marked size is W29 L30. Actual measurements (flat lay): waist 36cm, inseam 72cm. Please allow for some margin of error. Deadstock, unused, and unwashed, but there are wrinkles from storage. No claims and no returns accepted.
