If you like going to space then check out this Occupy Mars Astronaut T-Shirt.
The shirt shows the galaxy in the background with lots of stars flying around and in front of all those stars you can see an astronaut and he is holding the famous red planet Mars and there is a little flag on it like it is claimed by someone. Below the astronaut it says “Occupy Mars”.
So if you like people to go to Mars then wearing this t-shirt will bring that message out in the open as it is all about going to Mars to colonize the planet.
