The Iris Clert Gallery opened in 1955, in the middle of Paris's fine-art district. Yves Klein and Iris Clert first met in December 1955, when the still unknown artist approached Clert in her newly opened gallery, attempting to solicit his monochrome artwork. Klein persuaded Clert to keep one of his paintings, a small orange monochrome, as a trial run. She displayed the monochrome in the corner of the one-room gallery. The painting proved to be successful, and upon Klein's return, Clert invited him to exhibit a few of his monochromes in the gallery's first major exhibition in April 1957, called Micro-Salon d'Avril (Micro-Salon of April). Micro-Salon d'Avril consisted of over 250 artworks, no larger than a postcard, by over a hundred artists. Besides Klein, the exhibit featured works from Pablo Picasso and Max Ernst, as well as Klein's parents. The exhibition gained the small one-room gallery considerable notoriety amongst the avant-garde of Paris, and the single-concept-driven approach would become a distinguishing characteristic of the Iris Clert Gallery. Klein's showing in the Micro-Salon d'Avril also proved a success, and within a month, he had his own exhibition in the Clert Gallery: Propositions Monochromes (Monochrome Propositions).
