I've been saving this lovely 'eighteen' to celebrate all the numbers you see in Los Angeles. They are particularly fine in Venice. You just have to walk down the little roads running back from the sea to Pacific Avenue to know that residents really think about how they number their property! The ones who just use standard plastic self adhesive labels seem to be using it as an anti design statement, in the context of the overkill of some of their neighbours.

Numbers are usually huge, completely visible and can be very long. Gladstones, a fish restaurant we used to go to with the family, is 17300 Pacific Coast Highway (they don't bother with commas). Materials can be anything from rusty metal to glowing neon. I saw one yesterday made of buttons.
