Artfully reduced dance of colors that reveals itself as a sunset. This picture (I don’t know if acrylic or oil painting) is from the 1970s as far as I know. The artist is said to be from Spain. But I don’t have a signature. Can someone tell me who the artist is? What is the picture worth as an original painting? I call this painting just Sunset Painting, since I don’t know the original title. Size is about 44 inches diagonal.
