Original Script signed by 20 cast members of the Cosby show... the Last episode.  Signatures include: Bill Cosby (Heathcliff Huxtable), Phylicia Rashad (Clair Hanks Huxtable), Sabrina Le Beauf (Sondra Huxtable Tibideaux), Malcolm-Jamal Warner (Theodore 'Theo' Huxtable), Tempestt Bledsoe (Vanessa Huxtable), Keshia Knight Pulliam (Rudy Huxtable), Geoffrey Owens (Elvin Tibideaux), Raven-Symoné (Olivia Kendall), Erika Alexander (Pam Tucker), Ethel Ayler (Carrie Hanks), Allen Payne (Lance Rodman), Deon Richmond (Kenny aka "Bud"), William Thomas Jr. (Dabnis Brickey), Joe Williams (Al Hanks), Jay Sandrich (Director), Clarice Taylor (Anna Huxtable), Karen Malina White (Charmaine Brown) and Carl Anthony Payne (Walter 'Cockroach' Bradley). There are two unidentified signature that I cannot decipher. If someone would like to help, one of them is the bottom signature here (it was the one signature not on the front of the script). I think they may be John Bowden and Carl Lauten, directors of several of the epsisodes.  The other signature is just above the word "Duplicate".  I can send a larger scan if someone would like to help me out.  In addition, there are a few names of people I am looking for to complete the family of the show.  They are: Lisa Bonet (Denise Huxtable), and Peter Costa (Peter).  If anyone can help, please email  Thanks~!
