 "Hidden Faces" was the first of eight programs that NBC put in the timeslot of "Let's Make a Deal" between its departure and the expansion of "Days of Our Lives" to an hour on April 21, 1975.Of those eight shows, only "Three on a Match" lasted longer than a year.No episodes of this program are known to still exist, the tapes likely having been erased by NBC, per the standard practices of that time.
