This site has over 9,000 original pieces of Kenner history. These are the actual negatives and such of original catalogue and packaging images. Many --- like the two --- I've linked below appear to be one of a kind. Although there are also numerous multiples --- especially the 35 mm transparencies.
It was a total blast to just browse through.
Frankly, the prices really aren't outrageous. I blew just under a hundred bucks and got four really cool negatives that I will blow up to add some truly unique retro kitsch to my apartment.
These are being offered by the original photographer -- they all even come with a certificate of authenticity . . .
Aside, from that --- they are just so dang cool. It's definitely worth just a look if you have any interest in the vintage line. The images are simply fascinating . . . the details clear and sharp!
Here is a sample of one I just had to buy. Check out this groovy old TIE FIGHTER shot.
