During one weekend each summer, the streets of Larimer Square in Denver, Colorado, became a canvas for talented artists during the annual Chalk Art Festival. Onlookers crowd around the sidewalks to watch as the colorful art comes alive with one piece of chalk at a time. This mural was in progress at the time of the photo. The completed illustration by artist Naomi Haverland went on to win “Best Use of Color” in 2012. Her sponsor was Frank’s Greenhouse.
