It's amazing how 30-something years later, we are still discovering things from the early years of Transformers, for the first time.

Currently on ebay is a listing for a promo pack for the 1986 Transformers Movie, for us$825 plus postage.
There are some sample photos from the promo pack, which are mirrored here for when the ebay listing disappears.

It hasn't sold yet, but I have photos of these sample pages (and more) saved from February.... but I can't remember if it was at the archive in the first post, or from TFW and the source wasn't noted.
Either way, it would be a great and rare item of Transformers history to own, so I'm surprised it hasn't sold yet... considering how much people are splashing out on single (official and 3rd party) toys & licensed statues these days.
