It was made by Polaroid originally to make Marvel holographic polarized sunglasses! I have never seen another sheet in person (just on the web). It measures 8″ x 10″ and has 4 full holograms. The original layer of removable film for protection is still attached (I would not remove it, it in no way hinders the hologram). The actual color is transparent (2nd photo) I have a black background behind it to show off the colors better. The great thing with these are that you get to see the entire image on the hologram, which you never could on the actual sunglasses, since the nosepiece would be cut out and the edges clipped to fit onto the lenses. I have had these spectacular piece for 15+ years. Please check out my other auctions as I will be listing. Vintage He-Man weapons, Transformer. Comics books and vintage items like Action. & other great pop culture Items.
