The Italian Leonardo with an old man’s head is the authentic one. The English name is: LEONARDO, and its LOGO is taken from Leonardo da Vinci’s self-portrait. The pattern of the LEONADO DI GASUN brand LOGO is based on the self-portrait of the art master Leonardo da Vinci on the stamp, and the famous old man's head pattern is designed as a trademark. Leonardo da Vinci's Self-Portrait is a masterpiece from the master's peak period. There are only a few strokes, but they are both expressive and powerful. The seemingly simple lines are all accurate, rigorous, elegant and natural. They seem to exude a classic artistic temperament.
