The decision to leave was often made on the call from abroad of relatives or friends and also found comfort in the "emigrant guides" very often produced by countries that wanted to attract labor from Europe. They showed images of paradise on earth: boundless plains with exuberant vegetation, neat houses, orderly city districts.
These dreams on paper were unscrupulously exhibited by travel agencies and shipping company agents to convince the undecided to leave. Therefore, one can speak of a real "migratory lever" carried out with this system somewhat throughout Italy.
