The rainbow holograms feature 3 dimensional models of some of the more popular Dr Who characters. When viewed in strong white light the depth effect is simply stunning. The holograms are hot foiled onto postcard stock (size 105 x 148mm) and are integrated into specially commissioned full colour illustrations. Images feature Cyberman, Davros, Dalek, Sil, Sontaran, Sea Devil and The Tardis. A must-have for any serious Doctor Who collector and a rare piece of history!
