My Old Friend's Gift

This belonged to an elderly friend. Her daughter felt that Hannah would have wanted me to have it, so I do, and love it. It is painted on very thin wood, the paint is applied heavily. In the lower left hand corner is the following: NAN, and either C0z, C02, or LO2. They are literally carved into the media. Hannah believed it to be Peruvian....any ideas or knowledge would be welcome
