Through correspondence with several companies, I did pick up signatures of Monty Hall, Larry Hovis, Ron Greenberg, Bob Noah and perhaps a few others, along with plenty of letters from Barry & Enright (also including one about Private Lessons). Jack autographed my copy of the JOKER home game when we visited the show (which might be, in keeping with the question, the first true autograph), kept along with some other handwritten correspondence. Got Bob Eubanks' autograph on the photo from seeing his "Greatest Game Shows" event, his new book, and a first edition copy of The Newlywed Game. Also got Steve Allen's autograph on a VHS copy of clips from his Tonight Show and a book based on one of his old routines, "The Question Man." And an autographed picture of Ray Combs a friend got me during a Family Feud Grand Rapids promotional trip.
