In 2017 the international consulting firm Syntesa Partners and Associates charged us with designing a visual identity proposal for the Agriculture and Solid Minerals Expo 2017, Kaduna (Nigeria). To illustrate the event we worked on a symbol which conveys the idea of harmonizing mineral and plant kingdoms, both a potential engine of development in the country. The logo created represents, in shape and colours, the synthesis of a leaf (on the top) and a mineral stone (on the bottom), usable in several applications and promotional material.
