Randall Landers pointed out in a comment that we omitted SATELLITE IN THE SKY from 1956, so, here it is, making our list complete, thank you R. What a beautiful spaceship it is too, white no less!
Here's a small look at SPACE MASTER X-7 from 1958 as it has an encounter with a space blob and brings it back to Earth, photo found by Crashsq, thanks pal.
That was fun, I like putting things into order, can't believed I'm finally done... Check back soon for more cool junk from... THE DUNGEON!!
