This is a special message for those of you at Mythcon who came up and asked me about the story I mentioned, "The Wonder Worker of the Plains." And what a glorious story it is! I have found my copy of it in African Folktales, Selected and Edited with an introduction by Paul Radin. It's available at Amazon, but also should be available at most university libraries, or on JSTOR. However, I do now have a pdf of the story -- so if interested, send me an email!
As for the original version of the "Monkey Girl" -- that can be found in African Nights: Black Erotic Folktakes, selected by Leo Frobenius. (1971) And while this is the original cover the book -- I only saw it in one of those university featureless black-hardbound editions. But that art -- man, gotta love the 70's . I ordered a used copy formyself. It's been years since I read it and I am looking forward to rediscovering some great stories again. And here is the link to The Monkey Girl essay which was part of my presentation at Mythcon.
