Vintage 70s Levi's 501s straight fit classic lightwash jeans mid rise 32x28

This pair of 70s 501 jeans is my vintage grail! These I found at Cincinnati's Casablanca Vintage store, where they were labeled as 70s Levis. Unfortunately, for some idiotic reason, I ripped off the leather patch because it was fraying, which makes it hard to authenticate them, if any of you were concerned about that. These jeans are an icy blue wash, with all the typical hallmarks of the 501s, including the usual pocket layout and button fly. These are mid-rise and fit snugly from the midsection to the knee, with a straight leg down to the hem. The measurements are as follows. Waist: 32in. Inseam: 28in. Front Rise: 11.5in. Back Rise: 15.5in. Hem Opening: 8in. Thigh (from fly end across): 10.5in. Thigh (from crotch seam across): 11.75in.
