I don't know, to me it looks like its still on, but the pic is small and my eyes are old, well older anyways LOL. Do you have a photobucket account? Its free to sign up, takes just a few minutes and you can post some BIG pics. Does that side have a smooth surface? When you pull the membrane off, the surface looks kinda rough. Slide that knife right under the edge, just below the surface, and stick it in about 1/2", then pry up. If you use a good amount of force and the knife does not break thru, I'd say its still on there. If it tears thru, then it may have been removed. Baby backs usually cost more too when they are sold with the membrane removed, the additional cost for the convienence of having it taken off. What did you pay per pound for these? Also, this may seem like the obvious, but I have seen it on the labels where it will say "membrane removed". Check it out.
