A.Venturini was a forger from Italy in the early 1900's. He lived in Pisa, Turin and Florence.
According to "Philatelic Forgers, their Lives and Works" by V.E.Tyler, he made (or at least sold) forgeries of Swiss Cantonal stamps, French and French Colonies postage dues, Spain, Baden (see below), Monaco and Tuscany. He also sold Spanish and Portuguese colonies forgeries. If anyone has more information, please contact me! Also, according to the same source, he might have obtained his forgeries from Oneglia.
I presume these forgeries of Baden were made by Venturini. The
stamp forger Fournier applied the
perforations and cancels and sold them afterwards.
An imperforate 30 k stamp of Baden? Possibly a Venturini forgery.
