Just for anyone new coming into this thread, copies of Blowing My Hero are not available here any longer. There was a one-time sale of copies of the book with the Bukowski letters removed, but that one-time sale happened a long time ago, sorry. Asking Amber to send or sell one to you is not likely to get a response, so you might want to look for a copy elsewhere. You'll pay more, but you'll probably get a copy with the letters pages intact.
If you are looking for the Bukowski Society yearbook with the excerpt from the book, check Roni's web site, or contact him for more information.
