Did this show have "next episode" previews on its original airings?

I'm curious if anybody who watched this show on its original ABC run recalls whether there were previews for next week's episode at the end of the show.

Such previews were fairly standard at the time (STAR TREK and VOYAGE TO THE BOTTOM OF THE SEA had them, and so did the third season of LOST IN SPACE), but I don't recall ever seeing any for GIANTS. Not in syndication, not on the DVD, and there don't appear to be any on YouTube, either. So I guess my second question is, if there were preview trailers, do any of them still survive?
