How much are bus ads that cover the whole length of the bus?

Wizard of Alice:

My bus #41 is always covered with a huge sticker ad that covers the length of the bus like a condom. Who does this, how often, and how much?

Hope you save a lotta coin by taking public transport. To put your big grinny face on the side of a bus ain't cheap. Officially, bus condoms are called bus wraps. They're pieces of preprinted adhesive vinyl with one-way vision capability over the windows. You can see out but you can't see in. If you want to blame somebody for this new assault on our senses, try Supergraphics in Sunnyvale. They're the ones who came up with the idea that advertising wasn't big enough or ugly enough or in our faces enough already, and what we mostly needed was huge ads on wheels roaming around town. Your favorite TV anchors' faces on a monstrous scale, accented by roaring engine noise and diesel fumes. Anyway, you need to get a good picture of yourself, write some snappy copy ("Ray Vance says, Have a nice day!" Just a suggestion to get you started). Then you contact Sunnyvale and fork over about $10,000 for the materials and printing. Meanwhile, the MTDB, through its agent, will rent you the outside of the bus for anything from $3000 to $6000 a month for a full wrap, depending on the length of the contract. Then sit back and watch yourself drive by.
