The High Museum of Art in Atlanta had an amazing exhibit called “Place in American Art.” The exhibit was incredibly well curated and fit well with the High’s permanent works.
I especially loved the concise explainers for the works. I took a photo to remember some other artists to find and research.
I found the art from that era fascinating. It was a time of incredible upheaval in economics, and social structure. For fiction, I’ve read Erskine Caldwell’s books (which were also well liked by my Grandad) in addition to Flannery O’Connor and more recently, Over The Plain Houses. Rightful Heritage by Douglas Brinkley along with the Warmth of Other Suns also provides a lot of non-fiction background from that time period.
For in-person exploration, Jarrell Plantation is a Georgia State Historic Site in middle Georgia that is well-maintained (though a bit obscuring on the slavery part).
