I recently discovered Jiro Yoshihara & Gutai group
I've been exploring the world of Abstract Art recently, and I came upon Jiro Yoshihara. He was the co-founder of the avant-garde Gutai group in Japan. I really like his work. Here is a couple of pieces that were sold a few years ago. You can view more here.
And here's a piece by Shiraga Kazuo, another member of the Gutai group.
