TRANSFER VARIETY IN THE POSTAGE STAMPS OF THE ITALIAN REPUBLIC

By Associazione Filatelia Italiana Specializzata

This work, divided into five volumes, lists those small printing defects, generated by modest manufacturing inaccuracies in the preparation of the cylinder or the plate or even by poor cleaning of the tool, which are constantly repeated in the same position in all the sheets or at least in a large part of the them.
The typology of these peculiarities, such as dots, spots, colour marks, white dots or light spots, is very variable, and is depicted and described here in detail.

vol.1 - winged wheel watermark
vol. 2 - 1955-1960
vol. 3 - 1961-1966
vol. 4 - 1967-2006
vol. 5 - air mail, express, pneumatic mail, authorized delivery, parcel post, authorised private parcels, postage-due labels
