I am unsure if this should be placed into either the merch or seminar threads on the 50th. I wanted to provide this info, if it is misplaced, I apologize.
From the disneygallery.com website (and meant for attendees of the 50th merchandise event):
We are pleased to announce that Diane Disney Miller has graciously agreed to participate in the Celebrating 50 Years of Magical Memories event. She will be available to sign the newly re-released biography of her father, Walt Disney on July 16, 2005. Please note this item has been added to the Random Selection Process. Guests that have already submitted their RSP's, need not worry, this will be a completely separate RSP submission.
