Book Introduction: This book contains over 100 original street art and graffiti photographs taken in the City of Portland, Oregon, located in the pacific northwestern United States. Portland is a mid-size city, with 2.3 million residents living in the metropolitan area. It is known for its liberal politics, wet and gloomy weather, eccentric quirkiness, local food movement, DIY economies, craft beer, artisan coffee, strip clubs, skateparks, and bicycle-friendliness. The unofficial, but popular, city slogan 'Keep Portland Weird' is found on building walls, T-shirts, car bumpers, and bike frames throughout the city.

Even though street art is being embraced by cities around the world as a cultural asset, Portland spends $2-5 million annually in public tax dollars on graffiti abatement. It employs two full-time graffiti police investigators. It has a 'zero-tolerance' policy requiring that all unpermitted public expression be promptly removed (fines are hundreds of dollars). Removal of artwork from privately owned public spaces is common. In some cases, unpermitted mural work has remained for many years in certain Portland locations for various reasons. Designated legal outlets for open free public expression do not currently exist in Portland, such as Free Walls that are prevalent in nearby cities like San Francisco, California and Seattle, Tacoma, and Olympia, Washington.
