Descendants of Carlos R. Fredrikson, the pioneer Swedish missionary to South America, have deposited 90 pounds of rare Pentecostal publications in Swedish and Spanish at the Flower Pentecostal Heritage Center.
The shipping container (sent from Sweden and pictured above) included Pentecostal hymnals and books in Swedish and Spanish, photographs, and periodicals published by Swedish missionaries in Chile and Argentina. Periodical runs include: El Heraldo Pentecostal, 1934-1939 (published by Carlos R. Fredrikson in Buenos Aires, Argentina); El Heraldo de Paz, 1939-1940 (published by Otto Nelson in Buenos Aires, Argentina); and El Clamor, 1953-1989 (published by Iglesias Evangélicas Asamblea de Dios Autónoma de Chile).
