The copyright page begins with a standard (for today-but was it so in 1949?) disclaimer that all persons are fictitious. Contrast this to the frequently used assertion in the novel’s of Dan Brown of the FACT[ual] nature of his material.

The copyright is claimed by V. M. Straka (already presumed deceased) and F. X. Caldeira. In fact Caldeira could claim  copyright only to his own translation into English. The Pan-American Copyright Convention  is presumably The Buenos Aires Convention signed in 1910.

This entire page is fiction, the creation of the authors’ imagination, but it too mirrors the fact out of fiction of the Depository Bank of Zurich found in the DaVinci Code, where an actual webpage was created for the non-existent bank. Likewise a webpage was created for the fictional Harvard Professor of Symbology, Robert Langdon.
