Sesame Street Elmo and Ernie kids second hand figures (Loose)

In 1974, Jean-Louis Guillaud, general manager of ORTF's third color channel, commissioned Christophe Izard to adapt the American educational program Sesame Street for France, for the start of the 1974 school year. The program was called Bonjour Sésame, and was to last twenty minutes, alternating scenes with sculpted foam puppets and scenes with real characters.

With 13 minutes of Sesame Street and a four-minute animal documentary by Pascale Breugnot, Christophe Izard had to come up with an idea to fill the remaining four minutes. Surrounded by a small team, including Yves Brunier, he created the sequence for L'Île aux enfants, featuring the character of Casimir.
