CATALOGUE OF TWIN ISSUES 2009
KINGDOM - R.S.I. - REGENCY
AIR MAIL - ADVERTISING

Catalogue of Italian twin values, that is postage stamps with the same face value but different subject, divided by type and period of issue. The author has included only the ordinary mail and commemorative issues, as being part of the same postal service, thus excluding any possible combination with air mail, express, postage-due, parcels, as they are generally considered as "non-natural twins".
The catalogue presents Kingdom of Italy from 1901, Italian Social Republic, Regency, Air Mail and Advertising. As to Air Mail, there are not the specific issues for first flights, special flights, cruises, air express, any possible combination.
