Oh, how I wish I could attend this!
I was unaware of Christenberry until a few years ago when I was researching Southern artists and writers. As I became more familiar with his work and how he was inspired by Walker Evans, his photography and constructions simply left me in awe.
His early photographic work was with a box Brownie. I think he now uses 8x10. He works in color photographs, mixed media paintings and constructions. His main photographic subject is vernacular architecture. Even if you make it to the exhibit, some people here may enjoy researching him on the web or library. There are several books of his work available, most of them being catalogs from his exhibits.
