This looks just fantastic. The Guerilla Art Kit is by the wonderful Keri Smith, who, when not creating public-spirited art, writes the inspiring Wish Jar blog. Her new book is designed to "... help you find and release your inner artist or activist," with step-by-step exercises, cutout projects, and sticker ideas, plus fun exercises such as leaving books for strangers to find, chalking quotes on the sidewalk, making a "wish tree," guerilla gardening, or making your own stencils. A great way to give back fun to your community. Published by Princeton Architectural Press.
