Leather Black Motorcycle jacket with skeleton bones

I cannot find a name tag or a size so I do not know who made it or size. I searched and see there are several different jackets made like this. Bone designs are not the same. That being said not sure what it is worth, I have a feeling someone will tell me. Nice patina and jacket is heavy. Jacket has a lining inside for a extra lining but I do not have it. Jacket looks old, in good condition. Fits me like it is a 2X. Measures 25"s across the chest. Sleeves are 27"s. 28"s from collar to waist. Entertaining offers.
