Biblioteca Nazionale Centrale di Roma seems to have something in its catalog called "Giacomino e l'aeroplano"

I don't know how to link to search results (that's a problem with many websites), so you may have to go here and do your own search:

I am not adept at using this website because I don't know any Italian!
