Calendars are well known to be the traditional form of big business advertising. When German tea producer Hälssen & Lyon decided to do something different, it created a buzz among the creative design industry.

The Tea Calendar by Hälssen & Lyon is made from tea, nothing else. Real tea leaves were processed and compressed before being sliced into 1 millimeter thick squares. These squares were then stamped with the date and slotted together to show one week at a time. Creating a calendar made almost completely out of tea. A brilliant instructional tea concept was created for its paclaging – peel one off, drop in a mug, and boiling water, and watch as it dissolves before your eyes.
