		I say:

	Oh, I remember those, Ted.
	Yes, they were cue marks for local station breaks.  I believe they  
were placed about a minute before a local break.
	Not shown on this video is the final local cue which started 5  
seconds before the actual commercial.  The white rectangle would  
appear steady (not blinking), as I recall for 2 seconds.  These visual  
cues were used until around 1982 or so.
