Conrad Bain - Diff'rent Strokes

Well, this one is a head-scratcher. I sent Mr. Conrad Bain (he played Phillip Drummond on Diff'rent Strokes) a 4x6 photo, a letter of request and a self addressed stamped envelope. He sent the photo back, but he signed it on the back. Kind of weird, but the dude is really old. I would send off for other members of the cast, but most of them are dead. I didn't bother scanning this one because it is just a name written on the back of a picture.
