If you want to earn free Postcards and really help out, download the Postcards To Space Flyer(1.5 MB pdf) and distribute. When you email photos of 4 flyers postered around your native terrain, you'll receive a Postcards To Space Kit.

To make the flyers, download the Postcards To Space Flyer, print and photocopy it.
Trim along the dotted lines to make 14 tear-off tabs at the bottom of each flyer.
Grab your camera and hit the streets. Good places for posters include coffee shops, schools, dorm boards.

Postering is fun and easy. Find post-up boards in places you go malls, coffee shops, etc. Pin up a Postcards flyer and take a picture of it. Be polite to staff, post one flyer per board, 'canvassing' boards is mean. If you have them, carry your own pushpins and tape.

Don't forget to take pictures of each flyer after posting, it's the only way to confirm your work.

When you are done postering, email pictures of the posted flyers. For every 4 flyers that you post, you'll receive a Postcard.
