The Old Dark.....Charming little 1920s California split level cottage?

Both the poster for the film, as well as the dust jacket for the tie-in book, feature the same image: a woman's face that might pass for that of Gloria Stuart, a mustachioed visage that might be meant to represent Melvyn Douglas.....and a house which looks absolutely nothing - nothing like the one seen in the movie.

At all.

It's a cottage which would be apropos only if the artist had painted seven dwarfs standing in front of it.

In fact, it more closely resembles this:

than it resembles this:

Is there some significance to the sweet little cottage on the poster that I'm missing?
