You also find graffiti, much of it lame, some of it great. This piece is a black and red (heh) stencil, around a San Francisco Water Department access panel, poetically enough:
The text refers to the Bandersnatch, from Lewis Carroll's poem Jabberwocky. Here's some of the text in the artwork:
Deeds Not Words - Eclair Acuda Bandersnatch
I would rather drink Chanel No 5 than be caught drinking bottled water dead or alive - Bandersnatch
Bandersnatch imploring S.F. to watch Tapped the film.
BOYCOTT BOTTLED WATER!
Above and to the left of the bicycle is the word "Eclair" mirrored.
I'm intrigued. This may result in a new movie review in the near future.
