This is a mysterious pair of vintage jeans, they are in excellent condition with two fabric flaws as shown in photos. They appear to be a pair of JCPenney's Plain Pocket jeans from the early 80's that someone has sewn in a Levi's Big E Orange Tab into. Very bizarre move by the original owner who likely really wanted to wear a pair of Levi's without paying the price.
There are no inside tags but they measure to fit as shown below:
waist: 38"
inseam: 30"
rise: 13"
