Marja & Moes (education)
Educational material formatted as posters to attach to classroom walls. One subject on Mind-Mapping and one on Creative Brainstorming. Leading figuers are Marja and Moes, two class mates in their early adolesence. They are quite dear to me. The Mind-Map material has sold quite well over quite a few years and I still encounter it when I visit schools in my capacity of advisor in the development of creative thinking skills in schoolkids and teachers
