Filled with icons, emblems of their times, Pierre-François Grimaldi's collages bear witness to a joyful and colorful meantime. The thermal and colorful tones of the aged posters, with a retro feel, give a warm and warm atmosphere to the compositions. This time, the famous Laughing Cow by illustrator Benjamin Rabier is in the spotlight, but also the Avignon Festival of the 1950s and the Champs-Elysées metro. In front of the assemblages, we linger on a word from a poster that would have resisted, we imagine the entirety of the advertisements, analyze the details and layers, we plunge back into a Paris of yesteryear. Sometimes enhanced with a plexiglass box or on a zinc plate, Grimaldi's works come to life in different media and formats.
