1957 – “Romoletto” – (Italian)
See video clips here and here. I don't know much about Romoletto (also called "Romollo II" by someone else on the net). He was shown at the IV RASSEGNA INTERNAZIONALE ELETTRONICA NUCLEARE E TELERADIO-CINEMATOGRAPHICA exhibition in Rome, 1957. Maybe someone could offer a transcription of the Italian voiceover in the video clips.
