I can see why they'd be banned.
#3: The 10% would object to the use of the term "fairy".
#7: We don't need no stinkin' furren language ads
#10: Making a false statement (saying that ingredient lists aren't required for soft drinks). Of course, a current Autolite ad does the same thing, saying "If it has an engine, we make a spark plug for it". The Peterbilt of Natural Selection has an engine, and they DON'T make spark plugs for it (ditto a B4V with the 1.9 litre turbocharged engine).
#11: Should be for a beer that's WORTH being saved from burning.
#16: They need a more accurate packaging machine ("About 5"? should be EXACTLY 5 in a pack).
#20: Everyone knows Santa smokes a pipe, not cigarettes.
#22: Again, makes a false statement. "Set a lever for any stamp you want"? OK, I want a rare (and valuable) Inverted Jenny
stamp - postage meter wouldn't print it. Trivia: This ad is clearly from a very limited time period (late 1944 to September 1947). How do I know this? The phrase "As if I asked her to fly a P-80". The Lockheed P-80 entered service in late 1944 (until it entered squadron service, it is unlikely that anyone would recognize the designation), and was renamed the F-80 when the Air Force became a separate service rather than a branch of the Army.
