Imagine walking down a sidewalk in Germany and you see one of those old yellow phone booths from the 1980s. “Does anyone still use those things?” you wonder to yourself in German. Then you notice there is a postcard placed on top of the phone inside. Your curiosity gets the better of you and you open the door, step in and pick up the postcard.
Turning the it over in your hands you look at the image on the front. This is what you see:
“What’s going on?” you say out loud. You look around to see if anyone is watching. A quick check for hidden cameras in the booth and then you turn the card back over. After reading the instructions you decide to write a pleasant message and drop it in the post.
