Every color of skin received the inspiration and talent of internationally collected artist Antonio Diego Voci (1920-85 VOH-chee). About the turn of the decade 1960’s to 70’s was a period of experimentation with texture, sand paint, glass paint (requires cooking) and this one with several textures; a dark skinned person of wealth, and her servant.
