1927 or 1928? 

Quintana Condarco, Raúl de la, and Ramiro Duchén Condarco. Pasión por la palabra: el periodismo boliviano a través de sus protagonistas. La Paz, Bolivia: [s.n.], 1992. p 324 says that there is a record in El País that La Humanidad would have been founded in 1927, contradicting Lora's claim that it was founded in 1928. But I just get snippet view, and can't see the whole argument. Anyone would could sort this out?
