Here is my collection:
Every character from 1976-78 Fisher Price/A-Ha action figures/stick puppets (Rowlf, Fozzie, Scooter, Kermit, Miss Piggy, Animal, Gonzo)
Bookmarks (I just found them this past summer in Borders/Waldenbooks stores. They are plush figures from the waste up and they are attached to a flat red piece. So far I have Kermit, Animal, Beaker, Swedish Chef. I hope there are more).
Wall Paper:
This is my coolest piece. In the bottom right hand corner it reads "1978 Henson Associates Inc. " I have an unused half-roll and it has (in a 19 x 21 inch square) Swedish Chef, Bunsen and Beaker, Link and Julius, Uncle Deadly, Sweetums, Doglion, the Electric Mayhem, Rowlf, Piggy, Annie Sue, Robin, Gonzo, Fozzie, Statler and Waldorf, Fletcherbird, Beauregard, Crazy Harry, Jerry, Lou and Gramps from the Jug Band, and JP Grosse. I have a square of this framed because it is so freaking awesome.
