1950年代中期，羅傑・馬萊伯・納瓦爾的工作室鑽研法國畫家尚・克羅蒂製作的燈箱，透過組合、層疊和黏貼彩色玻璃片，將畢加索的畫作轉化為玻璃畫，並配合光線投射，製作成燈箱，重新演繹大師的卓越作品。

In the mid-1950s, the workshops of Roger Malherbe-Navarre expanded on the light boxes of French painter Jean Crotti by layering pieces of glass into pictorial depictions (gemmail, French for ‘enamel gem’) of several of Picasso’s paintings.
