^ XL5 aired in the U.S. on a major network in 1962. It caught my eye immediately because I was already a sci-fi fan and had owned marionettes. I even wrote them a fan letter and they sent back a little 5x7 photo of Steve, Venus, and Robert in Fireball Jr.
Wow! How cool is that! I bet that photo is a neat little treasure! Recently my fiance's somewhat-computer-unsavy aunt came to visit and she was talking about TV shows & commercials she watched as a kid. I got on YouTube and found them so she could see them again, THEN I showed her a Fireball XL5 clip to show her my FIRST favorite TV show....
