Yo brotha saw your comment - “ Haven't seen a guide with poster locations yet.
I had some issues with finding 3 of them - one was in Spirit's Cave on food cart; 2nd behind container on pathway from main area to first auction area; 3rd on outside wall of Aunt Mary's house.
There are 4 (or 5) posters in the area by Throwback Theater.
Cannot remember other locations. Maybe this will help a bit.”

That’s what someone wrote to me!

I don’t really remember the exact locations of any. There’s also a tricky one on your way to the first area to bid. You can chop the grass to the right and reveal a poster behind a wall.

du musst ein LP machen von Life is Strange ^^
