I have, but I don't know if he actually got it.
Last year, when I went to his concert at Casino Rama, I purchased a book by Dr. Stanley Coren about dog behaviours (Steven has a pack of dogs living at his house) called "How to Speak Dog".
I inscribed it as coming from here -
www.steven-seagal.net - but I was unable to secure a backstage pass (I found out too late that I did have the connections to get one - grr!).
I gave the book to a security guard that did have a backstage pass, after the concert.
I had put my business card in it, but I never heard back from anyone if he had, indeed received it.
