An unrecorded world map probably issued for presentation to attendees of the 1958 Lisbon conference on the International Convention for the Protection of Industrial Property.
The original Convention had been signed at Paris in 1883, its achievement grounded in “a realization that in matters of international trade self interest is synonymous with fair dealing, so that uniformity of protection of with regard to patents, trade marks, designs and indications of origin would be of benefit to all.”
The Lisbon conference had 250-300 attendees, representing 40 of the 46 countries signatory to the Convention. As I understand it, the main achievement of the meeting was an updating of the Convention to provide “for the protection of appellations of origin, that is, the “geographical denomination of a country, region, or locality, which serves to designate a product originating therein, the quality or characteristics of which are due exclusively or essentially to the geographic environment, including natural and human factors.””
The map itself covers the entire world on what appears to be a much-distorted Mercator Projection, compressed as one moves east and west from Greenwich, England and south of the Equator, with the result that only Europe is vaguely recognizable. The cartographer has added decorative elements borrowed from the 16th and 17th centuries, such as sailing vessels, a compass rose, a Baroque cartouche reminiscent of Abraham Ortelius, and a geometric border, giving the whole an Old World aesthetic. Several dozen countries are colored, possibly indicating either those sending delegations to the Lisbon conference or signatories to the Convention for the Protection of Industrial Property.
The map was published by the intellectual property law firm of Barzanò and Zanardo, based in Rome and Milan. The firm was created by 1906 merger of the Milan-based practice of Carlo Barzanò (1849-1915) and the Rome practice of Giovanni Battista Zanardo. Over the years, they became one of the leading intellectual property firms in Europe, filing patents and trademarks for some of the world’s most iconic brands. The firm remains active today.
The conception and design of the map are attributed to one “Humbertus Allionius”, the drafting to “Tiberius Nozius”. I am unsure who these gentlemen were, but perhaps the names are Latinized renderings of lawyers or staff at Barzano and Zanardo, or of employees at the Rome firm of Stabilimento Arti Grafiche Luigi Salomone, which printed the map.
The map’s lower margin bears an ink inscription to Arthur G. Gilkes (1915-1999), a Chicago-based patent attorney. Gilkes graduated from Princeton with a degree in chemistry, was commissioned as an officer in the Naval Reserve, then took a degree at the NYU School of Law. He began his career as a Standard Oil senior patent attorney in 1954, and attended the Lisbon conference as a representative of the corporation. He worked for Standard Oil until his retirement in 1980 then spent the remainder of his life in Northeast Harbor, Maine. The dedication appears to be dated 1957, though the cartouche bears a date of 1958.
Not in OCLC, and I find no record of another example having appeared on the antiquarian market.
