A difficult one this, I saw these on E bay as well, and it appeared to show selvedge. This design was availible as a black denim pre wash, thus the denim would be red line selvedge only and not the Red/green seen on the Indigo raw version.
However as you correctly point out one of the pockets should be of the skeleton woman, Ive personally never seen them featuring the same design on both pockets.
Not really seen many fakes in the black denim style to be fair, the waistpatch and swing tag look authentic too.
Given the pictures I'd be inclined to say these are genuine, perhaps its just an odd pair which had both pockets the same for some reason so that it matched other designs with double pockets. Its the Unlimited Sifr design so should have the text writing on the inside of the waistband ( see pic )
