When the MGEN, the historic mutual insurance company of the French National Education system, wanted to open up to the general public, and thus create a network comprising both sales outlets and medical practices, it was necessary to update its logo. Keeping the green colour and the star from the beginning (a star is a good omen and shows the way), NK Studio applied itself to make this old brand a “sign” with high visibility. It is therefore an exemplary signage work that has been carried out, capable of creating impact on the street corner, as well as developing identity signs in all communication elements.
