Fear not intrepid bloggers y rumberos, I may not be so fluent in Spanish, but I am handy with a scanner. So I've scanned some of the plates inside the book. The Arara drums are really interesting, and the captions to the plates are simple enough for me to translate. My favorite being this caption:
Figura #12 . Tres congas de Guantanamo, con simbolos lucumies, congos, nanigos y cristianos.Which roughly translates to: 3 congas from Guantanamo, with Lucumi, Congo, Nanigo and Christian symbols. The Lucumi are descendents of the Yoruba in Cuba and the word Lucumi I have been told means friends. Congos refers to the Bantu in Africa. Nanigos refers to the Abacua and the last is of course Spanish Catholicism.
Anyways, I'm lucky enough to live in San Francisco with it's large Spanish community, so I am happy to share these scans with you rumberos with less well stocked libraries.
