Two ads that I think are tremendous in getting to the point. The bottom says something like our 8 train cars hold up to 300 people. Then, it shows 300 cars with the train cutting right down the middle.

the other ad was just for fun. Scares me a little. I think of UV rays frying my brain. or abduction.

These are all from a book I purchased at an awesome old bookstore in Stokholm this December. Definately a worthwhile investment, and I don't get to say that very often.
