An Argentine Verbano hand painted small dish

Jesus teaching to four children. It is signed Alvaro 1991. I think tha the blank was sold undecorated and an amateur painter did this wonderful design. I bought it for a cents for a gift to one of my coleagues at the University. In Argentine there are two big china producers and Verbano is one of them, it was sold to a Portuguese firm in 1995 http://www.verbano.com.ar/Historia.es.php
