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 quite a fabulous abstract piece! It is popping with fun colors and was executed with acrylic on soft board. It is signed “P. Keil” in the lower left corner and was painted in Berlin. A Certificate of Authenticity from the artist is adhered to the verso. This piece was purchased by the Bowen family as a routine purchase directly from the Keil family, acting on behalf of Peter. This piece is in excellent condition with typical signs of age and wear with the exception of one very minor flaw in the upper right corner. See photos for a more detailed look. I do believe that once framed, the imperfection would no longer be seen.
