In 2007, Adam Feibelman developed this educator guide pdf for SPARKed (SPARK in education) to use for K-12 visual arts discipline(s). This was early-enough in the street art wave, and the websites and book resources are telling with their lack of content on what was happening in the streets beyond graffiti. A quick search in the pdf for "street art" found no results, but Adam does a great job, mostly citing Tristan Manco's writing, pulling all this public art together to show how it creates a "vibrant contemporary art form." Adam even includes posters and printmaking in the mix. Stencil Archive is not mentioned as a resource, but that's fine since Josh MacPhee's Stencil Pirates is included. The digital version of this book is available to check out on archive.org, and Stencil Archive contributed an essay and photos to that project.
