This scene in this episode is my first vivid memory of the show as a child; When it was just a show that my sister and her girlfriends watched. I happened to be passing through the living room and caught a glimpse of the TV: I was mesmerized!; Never saw anything like it on TV before (or since, probably) and it made absolutely no sense to me out of context. ...But I never forgot it, it was truely unforgettable.
Of course I was chased out of the living room the moment I started asking questions, lol.
It wasn't until after Petofi arrived in 1897 that I started watching the show on a regular basis.
It was something else seeing this scene some twenty-odd years later and understanding it completely while at the same time, going through my memory of the first time I saw it all those years ago. It was a great moment.
I really enjoy the pre-1975 storylines and have a big soft spot for the B&W episodes. The introduction of Laura is one of my favorite moments in the series. Classic top-notch soap stuff, IMHO.
