I'd love to have a signed photo of Mr. Jim Henson - my 2nd greatest hero next to my Big Brother Robbie who is now my Guardian Angel, a MTM screen-used Rowlf (from the dog kennel scene), a TMM screen-used Dr. Teeth and Kermit w/Banjo, a screen-used Sprocket from the final episode, brand new built OFFICIAL Scooter, Fozzie, and Elmo Muppets for my Son (his favorites), all the unreleased Palisades figures (Muppets, Sesame Street,
and Fraggle Rock), posers of all my favorite Muppets from every branch of the Muppet Family Tree, Gonzo's plumbing truck from TMM, and blu-rays of every Muppet EVERYTHING with gads and gads of extras.
I'm sure there's more, but from that list I'd settle for, well, okay, I really want everything listed, lol.
