Last month there was a very interesting exhibit at "Le Bon Marché", actually 2! The first was on Aristide Boucicaut who created what is considered the first department store 160 years ago. The second exhibit above, showed 160 years of graphic design done for the store, which I would say was characterized by amazing creativity and variety. Click to blow up!
Uh Oh... just checked and saw that the picture above was ridiculously tiny, sorry about that!
