I found this neat 1964 photo in a magazine featuring an RCA color camera at the WNBQ studios in Chicago filming a quiz show called "It's Academic" with contestants from my home town. I'm not sure what model the camera is though, a TK-41?

When did Channel 5 become WMAQ?

Any chance you can shrink the picture? My little 14" monitor doth protest.
