1957' broadcast of Cinderella on CBS? IN COLOR!!

[3Guncolor]

1957 is a bit early for color video tape. CBS was using Ampex qaud but it's possible an RCA quad at NBC was used to record it in color.
I think RCA was testing recording color around that time. The big problem today is if a tape is found it very hard if near impossible to get it to play back without banding ect.. but it has been done.
There are good working quad VTR's out there for stuff just like this.
