It is the finely balanced abstract shapes which holds the viewer’s attention along with the contrasts between colored linear lines contrasting with the strong solid shapes. It is an oil painting on canvasboard. It is signed “Ch Biederman” in the upper right corner. The size of the image is 10′ X 16. It is in excellent condition. The outside dimensions of the frame are 25 ½ x 21 ½. It is framed in a grey wood from which has a few dents with a linen and grey wood liner which has been. Decorated with red swirls. I have checked to see that the signature matches other of the artist’s signatures and that the style is similar to other pieces and that the palate is in keeping with other paintings. This is as far as my research goes. There is no Certificate of Authenticity. There is no provenance or background information and the price reflects this aspect. Thank you for looking at my listing.
