LEONI SERIES
Study of print runs

This volume deals with the method of printing "typographic" postage stamps with royal effigy, starting from the first series of the Kingdom, up to the dawn of rotogravure printing, in particular the Leoni series.
Relevance was given to the plate numbers, through which the chronological reconstruction of the different print runs that followed one another in approximately a quarter of a century becomes possible.

Research conducted with a scientific method and adequately in-depth allows us to compare the results and verify the validity of the hypotheses made following the analysis of large quantities of specimens and historical sources.

The aim is to collect, in a single text, as much information as possible on the topic of Italian typographic postage stamps and, at the same time, make readers participate in this research, show the new evidence found and provide tools and methods to those who wish to undertake or deepen the study of this branch of philately.
