These are Levi's 501 denim pants from the 1980s. This is a model from the transition period when the red ear was discontinued and changed to regular, and it features single-stitch construction on the inseam. The paper patch has the "CARE INSTRUCTION INSIDEGARMENT" print, which can also be seen on red ear models. The model number 1501 is assigned to models with a W36 or longer inseam. The color remains at about 40%, with fading typical of 1980s regular denim. The model with the single-stitch inseam, which was only seen during the transition period from red ear, was only manufactured for a short time, and the lot number assigned to long inseam models is thought to have been quite limited compared to regular sizes.
