Definitely fake, sorry. You have yourself a fake Longchamp Type S. The leather on all Pliages should have a diamond pattern on the grain. That's usually the easiest way to ID a fake.
Other bad signs on your bag: Handles have plastic tubing inside, which they shouldn't. The handles are also made 2-ply leather. It should be one layer of stiff leather, and the leather should be raw on the underside. The textile is too smooth as well.
Just noticed the rest of the album. There shouldn't be a seam across the bottom of the bag, and the seams are covered with the wrong type of fabric. It's missing the heat stamp on the black of the leather flap, not to mention the leather is the wrong color. Zipper pull looks fake, and should say "1948" not "Paris" on this type. It's a pretty bad copy.
