The statue will be presented to the pope next month by Italian actor Barbato De Stefano, who comes from the village of Cicciano where it was presented and has financed the project.
"The poverty of my village is a treasure for the community in which I was born and grew up," said De Stefano, who praised the pope's own modest demeanour saying he had "pierced people's hearts".
The primitive-style statue was shown yesterday, with a painted background of the balcony of St Peter's Basilica on which the pope stood after his election at a conclave of cardinals in March.
The 76-year-old pope was formerly the archbishop of Buenos Aires, Cardinal Jorge Bergoglio.
Like many Italians, his parents emigrated to Argentina between the First and Second World Wars.
