Acrylic on heavy paper. Excellent color and texture. Classic abstract from this talented artist. Signed on recto and en verso, framed in wood, and ready to hang. The dark brown/purple striations on the frame complement perfectly the dark brown/purple paint strokes and the gold wood frame liner makes the yellow flowers pop. The straight lines of the frame give definition to the floopiness of the piece. A fun piece at a good price point. Thank you for your interest and please let me know if you have any questions.
