Like Francois Fournier, Imperato promoted his forgeries as facsimiles available to the collector at a fraction of the cost of the real thing.
His house journal, Il-Fac-simile, went through at least nineteen editions between 1920 and 1922.
[2] Amongst other content the journal included two short articles by fellow forger (or distributor of forgeries) Angelo Panelli.
Forgeries were produced of a wide range of stamps, including:[2] Many other were offered too but it is thought that they had actually been produced years earlier by Erasmo Oneglia of Turin.
[2] Robson Lowe and Carl Walske speculate in their book on Ongelia that he retired around 1920[3] and it may be around then that Imperato acquired his stock of Oneglia forgeries.
