This is a fun poster which was forwarded to one of the scooter forums I visit. I have no idea where it came from, or who made it. However, it sure is fun!
Now if you are in San Francisco, and want to get some coffee, you should go to one of the "Lambretta Cafes". Some well known local scooterists have set up several coffee shops/stands throughout the city, and all have a Lambretta theme. If that were not enough to entice you, I can tell you from personal experience that the coffee is excellent. Get a cup, and support some good people!
