When will the aliens come back?

 

When are they coming back? Did the aliens build the pyramids themselves or did they enslave the Egyptians to do so? Are they actually landing pads? We shall see soon.  Or at least this poster says so.

While you're at with the alien conspiracies, why don't you sign up to join the Lunar Colony. Coming soon...

Thinking of Moving? Join the Martian Colony!

Need a change of (s)pace?  Tired of the same old terrestrial surroundings? Take a trip and join the new Martian Colony!

Sooner or later, we'll see travel posters/recruitment posters such as this one. Don't wait. Put this poster on your wall and start taking volunteers to help rocket humanity to the future.
