Slender: The Arrival

This trophy is awarded for picking up the large sign collectible in the second level, The Eight Pages ("Oakside Park has 3 canoes available for rental"). If you're following the collectibles guide video, it will be collectible #17. If not, it's easy enough to find without a video - as you enter the level proper you will undoubtedly come across a small building, and on this building is the large wooden sign.
