Since I just got done watching another ep of Game Show Marathon (Beat the Clock), I was in a game show mood and I stumbled across a site that has an entire ep of a nighttime version of The Price is Right from 1972 (the 6th episode--aired sometime in October 1972).
Notice the first (little known) black Price is Right model.
Anyway, it's the same show you all know and love in a different time. Check it out:
