Kathryn Cody Russell didn’t know that the Maine Organic Farmers and Gardeners Association was celebrating their 50th anniversary when she designed her submission for the organization’s 2021 Common Ground Fair poster contest. Instead, her riff on MOFGA’s iconic logo — replacing the tree’s trunk and boughs with colorful produce like carrots, peppers, blueberries and potatoes — came from a brainstorming session with her husband, Michial, the final week before the submission was due. “I’ve always been very drawn to trees, both in nature and in artwork,” Russell said.
