William Christopher and Harry Morgan questions/ advice

[moviemac88]

Hey I was just wandering if who has had success with the address in the database for William christopher, and if its better to send a pic along with a letter and SASE, and if possible the sent and recieved Dates. Also I really want atleast Harry Morgans autograph I've tried a acouple times but only sent letter, this time I'm going to send letter, SASE, and a booklet from the fourth season of M*A*S*H, what are the chances I would get this back signed do u guys think? Also do u think it would be good to send the booklet from the 11th season of M*A*S*H to William Christopher, what's the likelihood. that I would get this back signed?
Thanks guys
