Younger Ray with one of his Skeletons. This might be the one from Seventh Voyage of Sinbad, which knocked my socks off as a kid in the mid '70's at a Drive-in in the San Fernando Valley.
More skeletons, these from Jason and the Argonauts, one of my favorite of Ray's films.
...and a still from Jason, utilizing Ray's puppets. I still think it's amazing he kept track of each of the skeleton's movements and moved all of them frame to frame to achieve this illusion.
