Anne Frank was Jewish and wrote a diary during the Nazi era in which she describes a chestnut tree in detail she could see from her hide. Since there are already many logos with the signature and portrait of Anne, the tree emerged as a suitable path. It provides a significant reference to Anne Frank and the tree also symbolizes growth and a wide range of opportunities for children to develop, as well as grounding and stability. The idea of a letter tree came about – created only from letters. The charm of this idea is to have a legible pictogram. Individual elements become a colorful whole.
