Even though I didn't have tickets to Comic-Con, I went down to San Diego last weekend to try to meet the Muppet performers. I didn't see Eric or Dave, but I did manage to catch Bill and Steve, and those were the two I needed to complete a couple of autograph sets.
I have a Fraggle Rock annual that I took to MuppetFest, and I got it signed by Steve, Dave, Jerry, and Karen. Jerry was the only one who also signed for his character. It stayed that way for about ten years. A couple of years ago things started falling into place, and I got Kathy Mullen's autograph and the rest of the character signatures, completed with the addition of Wembley last weekend.
I also have a Muppet Telethon program from "The Muppets". Since it is a prop program all of the pages are blank, so I turned it into an autograph book. It now includes all of the main performers from "The Muppets", and their characters, plus James Bobin, Nick Stoller, and Jason Segel.
I have images on a photo sharing site, but I still can't seem to figure out how to include them here. If you would like to see them, you can use this link:
