LV: Is this real leather or not?

Hello all!

Some days ago, I received a nice piece of material with the Louis Vuitton monogram (it is an original piece that someone got from one LV atelier in France some years ago and now is in my hands).

I did a kind of "autopsy" this afternoon using the skiving techniques in Phil's videos ;P to see how it was inside, as it looks pretty much like plastic.... the point is that, far to find leather inside, I just saw this:

So, I don't know what to think. I thought there was something nice inside, but this thing looks to me just like a coat of plastic or rubber over a sheet of fabric or so. All the lighter brown part in the picture is like rubber. Maybe the piece of leather is soooo thin that I can't see it well? or I am the silly one who thinks LV doesn't make plastic bags...?
