Find all the posters in Amerykan dream. There are 18 in total. I can’t remember where all of them are but
If you are having trouble the ones I missed are these 2
1) in the entry way to the theme park. (Knock down the cardboard palm trees and bushes then crouch under the gap)
2) in the first area in Mary’s house go to where the auction bins are then to the left of those go to the fence and look on that back corner of the house.
