Don't we just love creative advertising like this? Congrats to Cramer-Krasselt for working with COA Youth & Family Centers in coming up with this awesome campaign. To help promote parent-child interaction, they set up large puzzles, word searches, mazes, books, rulers and more around the streets of Milwaukee. Called "guerrilla classrooms," the displays are designed to teach real-world applications on various subjects like math, science, geography and reading. The ultimate goal? To raise awareness of the positive impact parent's involvement can have on their child's education. In addition to the billboards and bus shelter signs, four Milwaukee Country Transit System buses were wrapped with destination experiences like a safari or submarine.
