The only early station ID that I know of is the famous KARD 3 Wichita, Kansas ID before the broadcast of An Evening with Fred Astair from 1958. This was the first program to be prerecorded and edited on color video tape. Some shows were prerecorded on color tape before this but they were recorded all the way through in one shot as if live with no editing. I stole my avitar pic from this video
