Puzzle seeks readers

Mysterium SFLB has launched an enigmatic campaign for an unknown client. This advertisement deliberately aims to be one: it is a 1/1-page advertisement consisting of nothing more than a riddle with lots of difficult questions. Advertisements that contain no customer logo and no advertising text and are therefore a real puzzle for every viewer. What is it all about? Only those who take the trouble to solve the puzzle will find out.slashes as a clue For advertising insiders, the enigmatic advertisement was also signed a little enigmatically, but only a little - the slashes in the signature refer to Spillmann Felser Leo Burnett. They confirm that they created the enigmatic advertisements, but won't reveal anything else. Martin Spillmann: "As our target group has extraordinary knowledge and great interest, we decided on this form. Anyone who can solve the puzzle really does correspond to our select target group. And they will also be rewarded."
The puzzles, which appear full-page in NZZ am Sonntag, NZZ Folio, Dezember-Du and WoZ, are not to be solved. Spillmann: "It is the first campaign that only our target group can decode. For everyone else, the riddle will remain a riddle forever."
