Some of those '33 Kong covers aren’t bad at all!
The '76 ones at least use some elements of the original poster art.
I thought that last one that totally spoils the ending actually said LGBT King Kong. I don’t think the pictures on the back are from the movie?
And again Carlo Rambaldi gets credit for the effects when his giant mechanical monkey barely worked at all and is in only in a few shots of the movie. It’s a wonder if Rick Baker never sued over that.
Rambaldi also designed the mechanical effects of the animatronic mask that Rick Baker wore.
