The concept of this calendar is that, each day, you take out the "sticker of the day", so you discover what is behind the number, a door or a window from the city of porto alegre. each window has curious stuff (a person looking, some graffiti, or, in special days like christmas, a face in a red door like santa claus). When the year is finished, you have a poster of all the images organized by colors, becoming a pleasant color gradient.
