This page of The Last of Us game guide contains information on where to find the comic books in the Lakeside Resort chapter. Those items are collectibles-secrets. Our walkthrough indicates the exact location of each artifact and pendant.
Comic #10 - Uncertainity
As you follow the wounded deer, you will reach a chalet.
Right after entering, turn left and you will find a desk in a small area. The comic is in the drawer.
Comic #11 - Negentropy
As you go along the lakeside, you will reach a short red pipe.
Walk over it and climb the stairs to the left. This will take you to a bench with the comic on it.
