Holograms...and Knights...and Holograms...and magic...and holograms...and science fiction...and holograms. HOLOGRAMS!!!!!! That was the selling point because, for about a decade until the magic eye paintings took over, holograms were the coolest thing on earth...especially if you were as old as I was. And that is what both the super expensive toys and the cartoon was about, holograms...more the toys than the cartoon. But, who cares anyway, this custom made to appeal to little kids and it did it in spades.
