Peter Keil is a German artist that focuses primarily on abstract expressionism. Keil painted with some of the greats including Joan Miró, Pablo Picasso and Andy Warhol, to name a few. This is such a fabulous abstract piece featuring a marble technique executed with acrylic on soft board. It is signed in the lower right corner “Peter Keil” with an unreadable location. A Certificate of Authenticity from the artist is adhered to the verso. This piece is in excellent condition with no flaws or chips to the paint.
