While news remains slow on Transformers: Dark of the Moon, the Disciples of Boltax has posted PDFs of Hasbro's Briefing Binder for the Transformers cartoon series. They broke it down into about 6 parts and made the scans available for download. The binder was part of the writer Ron Friedman's auction that had included the Transformers: The Movie draft script.
The briefing binder shows of the first designs of many of the Transformers, early pics of the toys, background art, ship design and more. It’s a fun walk down the origin of the cartoon series that laid the groundwork for all that has followed including the movies and shows the kind of prep work that went into the cartoon series. Below are the links to Boltax's posts about each binder section which also contain the download links if interested in looking at the PDF scans.
As a bonus, click here to look at the "Pre-Toy Fair 1985" images that first introduced the more or less the second wave of Transformers including Shockwave and Jetfire. I still remember when Transformers use to take up an entire long aisle of these old style boxes at Toys R Us and Lionel Toy Stores, always fun to visit especially when flush with cash after Christmas. If only I had done a better job of saving all the packaging and accessories.
