i'm guessing the actual image itself would be a VERY high resolution vector. so that would bring in the possibility of AI filters and effects rather than photoshop however. it looks like a mixture of noise, photocopy, and Poster Edges overlaid on top of eachother with different setting and the noise layer would have a layer mask to moderate it's position.
I used to do this manually before PS came along.
