This is a kinescope of (obviously, given the long awkward silences) a live stage show which was typical of very early TV. Nobody knew how to use the new medium, so when they weren't doing "radio with pictures", they were just filming vaudeville shows that had been running for years. Ed Sullivan somehow kept this ancient format going into the early 1970s. There were no re-takes, so glitches and ill-timed entries were common. I'd put this ad in the late 1940s, likely on "the DEW-mont Network" (infamous for the fact that when it went bankrupt, most of the kinescopes were quite literally dumped in the Hudson River). We get a good long look at this fierce-looking thing with the bared teeth, but my favorite bit is where they demonstrate just how easy it is to CLOSE THE DOOR - and, even more alarmingly, how easy to open it. That heavy, four-foot-wide passenger door they've just bragged about literally opens at the touch of a finger, so it won't slam on your feet or ankles (which it wouldn't anyway!). But just think about it. Seat belts literally did not exist back then, so one tiny touch would pop the door open like a jack-in-a-box and eject whoever was in the passenger side with enormous force. But, as they used to say in the bad old days, you don't need a seat belt anyway because in the event of an accident, "you'll be thrown clear".
