Here is a title bumper card (I think that is what they are called) for Dark Shadows. This is obviously later in the run of the show (1970), because it features Roxanne Drew (Donna Wandrey), who was Barnabas Collins love interest at the time. Also, you'll notice Jonathan Frid's hair is not in those plastered bangs that he wore in the earlier episodes.
The title bumper card usually was seen when the network was having "technical difficulties."
