I purchased an 8x10 of Bob Newhart in Elf recently off of ebay and I told myself that I would get it autographed. I know that other celebrities autograph items if contacted by mail (mostly game show panelists, Richard Dawson, etc) and Bob has an address on his official website. I was wondering if anyone has actually used this address and had any type of success.

My friends also bought me an original "The Bob Newhart Show" press kit from the early 70s. That could be better for him to sign. Any help appreciated.
