This is an image of an 8"x10" photo of one of Lou's covers.  The genre is late 1940's judging from the poster for the 1948 movie "Lady on a Train."   We haven't determine what the illustration was for.  The paper is heavy photo stock. 

Lou photographed many of his works at this stage of his career because he knew that art directors often kept the originals.  Although that practice diminished greatly after artists began putting limited rights notices on their bills of sale and invoices, it never stopped completely.
