From another source, with search links added:

“Lawyers for the Austrian government have fought since 1998 to retain the rights to the four paintings. The other paintings are a lesser-known Bloch-Bauer portrait [possibly your #2], as well as Apfelbaum (Apple Tree), Buchenwald/Birkenwald (Beech Forest/Birch Forest) and Haeuser in Unterach am Attersee (Houses in Unterach on Attersee Lake).”

Thanks for the links. You are an internet whiz (or maybe I just give up too soon).

Here are the probable images: Apple Tree, Beech Forest/Birch Forest, Houses in Unterach on Attersee Lake

I like the forest best. He has such a wonderful sense of overpowering texture. I know I'm repeating myself, but that's what draws me into his work.
