Raul Leoni (1905-1972) was president of Venezuela from 1964-1969. The Venezuelan rule for anonymous works is 60 years from publication, so this is likely still under copyright in Venezuela. However, in order for it to be free of the URAA copyright, it would have to have been published before 1936, when the subject was only 31. That seems very unlikely -- he appears to be at least 20 years older than that. There is no basis for the CC-BY license -- indeed, an anonymous work cannot have a CC-BY license because there is no one to attribute it to.
