Printer’s sample proof sheet with 1929 Italy, 1929 Vatican, 1931 Tripoli and singles from south Africa and the Argentine. The majority overprinted Saggio (specimen) includes a silver-grey Italian printer’s sample (perf. fault) with Saggio printed in the country tablet. Legend at foot reads:

“These stamps are manufactures in rolls and sheets on our poststamp printing machines working on the copper-Plate method in one operation@

A very unusual piece.
