This calendar was sent as a direct mailing to BASF’s business partners. The idea for the design of this original promotional material was inspired by the chemical tests, experiments and research taking place in the company’s labs every day. The new annual calendar seems like a daily experiment, reminding the target group about the importance of chemical innovations. Twelve test tubes of different colours represent the twelve months of the year. They are filled with coloured aqua. Evaporating through the open lid, the liquid level indicates the date of the month and the day of the week.
