On the occasion of 50th anniversary of Cobra lamp designed by Elio Martinelli (Lucca, 1922 - 2004) founder of Martinelli Luce, the company presents, in the spaces of the Galleria dell'Architettura inside La Triennale, a monographic exhibition dedicated to him. The exhibition certainly does not want to be exhaustive of the thought and planning of Elio Martinelli in over 60 years of activity, but only a tribute to a designer and entrepreneur who has contributed to the diffusion of "Made in Italy" in the world. During the exhibition the visitors will also see the versions of CobraTexture project.
