It's really very simple.
Take one of our free Postkarten, stare at it in awe, then write words on it, stamp it, and post it to a friend, lover, or neighbour. Or worst case, yourself. Then prove this has happened (Instagramming @dasautomat is easiest but you can bring it in if you didn't post it very far away) and we will bestow upon you a free t-shirt of your choosing.
Small Print (To be honest, it's pretty much the same size as all the other print)
Because we're convinced you're all too busy to actually write letters with pens our aim is to grant a free tee to anyone who provides a postmarked card to show just how awesome we think they are, however in an effort to avoid bankruptcy, we will limit this to one shirt a week. First proved, first served.
