These are great, the design is the same, & aside form the normal Kubrick articulation, they have removable domes, moving jaws, & extending inner jaws (controlled with a tab under the back of their head faithful to the 79' toy). 79's Skull detials are GID and the toy comes with a poster.
The movie colorway has blue lines and a dark dome, the 79' version is faithful to the toy.
Also notable is the fact that the 79' version comes in a box that is as close as you can get to a reproduction of the original box and still fit the Kubrick in it.
Also for sale is the 100% versions of each. Pretty amazing, as they have the same articulation as their 400% counterparts down to the inner jaw sliders. Even the 79's box is a reproduction.
