This achievement would be EXTREMELY hard to miss through the game but you can get it on the very first chapter after speaking with Sarah Hawkins Father. (Forgot his name, I will call him Colonel Sanders)
First, look at the newspaper clippings on the desk, turn around and view the painting on the settee, you should then fail that and unlock this achievement.
Very Easy, go to 5:20 in Playthrough 1 video to see this.
Hope this helps!
