I have just put a short listing of myself on ebay. You can find it here: Arnold Perey, anthropologist, Aesthetic Realism consultant.
If you're registered on ebay yourself, you can have a page too. It's a very visible Web site and people can pretty easily find you there and see what you want to say. Some of my enthusiasms are posted there, in outline form, and soon I'll go back and write a bit more.
Eventually I'd like to have my new book Gwe,Young Man of New Guinea: a novel against racism on ebay and see if it's practical to sell copies there.
