This article on Cezanne led me to think about how Theo had occasionally painted over finished works due to the lack of materials. I often wonder if I will ever see them again.
I have a photo of a portrait that Theo did of me in 1992. He painted my portrait over what I consider to be an important painting... : \
Unfortunately, I am still trying to figure out how to download photo's on here...lol! Working on it today.
