To Kill a Mockingbird- researching without too much influence

Without referring to the film as too much of an influence on my stylistic choices, I have been struggling to really picture the sort of environments and clothing choices that would be accurate to the time period/ location of the book. The courthouse images have been useful, but it was hard to find images of the houses in the film. However, a simple search for 1930s houses in Alabama brought forward what I thought might be accurate. As mentioned in PPP I'd like to work with more 'environment' lead illustrations, I think To Kill a Mockingbird could potentially bring this forward, but there's also a lot of scope for something minimal/ symbolic, or character driven too...
