landscape painting classic modern art signed and delivered with its certificate

Acrylic canvas mounted on a 20x20 cm frame, painting of a landscape "the lake of water lilies", I used several shades of green and yellow to bring out the light and the brilliance of the sky. The work is a unique piece signed and dated, delivered with its certificate of authenticity. Possibility of framing it (American box) to give more depth to the canvas. The edges are painted black which gives it a modern look once hung.
