A website called CitID is collecting logos and artwork for cities all over the world. The rules for submission include that the arwork must contain the name of the city and should (if possible) aim to catch the vibe of the city (If you’re at artist, consider submitting your design!).
Currently three designs have been submitted for Portland. They’re all kinda groovy. I can’t say which one I like best. They all include rain! Below is a sliver of each (click on image to be taken to the full image at the CitID website).
