GRIMMWELT Kassel brings the work of the Brothers Grimm to life, from their fairy tales to their linguistic research. In 2025, GRIMMWELT celebrated two anniversaries: ten years since its opening and 20 years since the Brothers Grimm's personal copies of the Children's and Household Tales were inscribed on the UNESCO Memory of the World Register. Machbar developed an anniversary campaign rooted in the existing logo. Two additional strokes transform its lines into the number ten. This subtle intervention gives new meaning to a familiar symbol, visually uniting both anniversaries while evoking the Brothers Grimm's handwritten annotations. Under the theme "Weitererzählen" (Keep telling the story), fairy tale motifs meet bold colours and playful animation. The campaign thus connects the Brothers Grimm's scholarly legacy with an invitation for visitors to explore it themselves. Because ten years of GRIMMWELT is just the beginning.
