I wonder how this would be accepted if it were from a modern cartoon? Not too well would be my guess. Apparently, during it's first season, The Flintstones was sponsored by Winston Cigarettes.
Now, I'm not saying that I agree with this at all, but it is a piece of historic mid-century Americana, and when I ran across it, I felt like I just had to share it! Of course, American culture has changed greatly since the introduction of The Flintstones (and so has our knowledge of the danger of smoking). Back when this came out, many people smoked, and was considered the "in" thing to do. It's a short little video, just a little over a minute long, so take a moment and check it out!
