It's been reported elsewhere, but there's a huge auction at the moment of very early TF designs / scripts by one of the guys who worked on the cartoon. Details of the lots here:
Jim Sorenson is currently raising money to attempt to buy some of these items with any money left over going to charity, like the recent-ish purchase by tfwiki of the Hasbro toyfair mag from the 80s. Might be something some of us want to chip in on, I personally will once I can sort my paypal out!
