I'm Dickens... He's Fenster is one of those TV shows that I have never seen or heard, but I know about - because my parents remembered it fondly. It's one season on the air (1962-63) occurred before my birth, and didn't yield enough episodes for any subsequent syndication.
Not surprisingly, there is a website devoted to it. This one appears to be an official attempt by the original creator of the show to get the thing released on DVD. (Hey, they released Good Morning, World, why not this?)
The site contains a clip of the entire first episode, so check it out.
