Designed by the Rispal in-house team in 1950, this lamp was surnamed the Mantis lamp because of its insect-like appearance. It was revealed to the public at the 36th Interior Designers Fair in Paris in 1952. First launching with a classic lampshade, it took on the iconic saucer lampshade in 1955, made with pleated cellulose acetate film – commonly called rhodoïd.
