A major issue on a small format. Encompassing the environment, economy, social affairs and art, sustainability is an extremely diverse and multifaceted topic. All of this can be discovered in a playful way on the new special stamp “Sustainability”. The special stamp is the result of a design competition organized by Swiss Post in conjunction with the Bern University of the Arts. 22 highly dedicated students in their second year of the Visual Communication course were given the task of presenting various dimensions of sustainability in a positive and appealing way in form of a stamp design. After learning and testing various creative techniques, they worked in groups to create extensive visual worlds. All the students then continued the work individually, with close support from their lecturers. The result were 22 varied, astonishing and highly original designs, from which the best eight were selected and presented to the Stamp commission in the final round.Carole Kiechl’s design was declared the winning design. The stamp is designed to encourage people to complete the word search puzzle – both before sending and after receiving letters. As well as the already circled word “HELVETIA” and the face value “100”, there are 24 other German, French and Italian words related to sustainability to be found. How many can you find?
