First blogged by me in this 22 December 2013 post at Infernal Wonders, this little pair of illustrations appears to be promotional art — possibly run in local newspapers — for the 1959 sci-fi cheapie Teenagers from Outer Space. I’ve seen this movie (or at least, the send-up of it done by MST3K), and I can attest that it does at least have the scene promised by the advertising. If you really want to, you can watch or download the movie the Internet Archive, or watch it as embedded here:
The MST3K version is currently available at YouTube, though I shan’t make any promises about how stable it will be.
The skeletonizing Ray is a brilliant example of replacing expensive special effects s with editing.
