Artist Neal Adams Final Paintings. As the years progressed Neal developed his work to a degree of understanding or non understanding. His art tied into his spirituality. Neal believed that aesthetics had an intelligence, language and truth all its own and belonged next to the spirit, a higher truth than words could express. His work is a conversation in itself. He reasoned the same lines, shapes and tones make up figurative as well as abstract art and pushed his work to emphasize the beauty of a line, depth of shading and the richness of color.
