NPB Studio and Tracee Badway created this “very funny” chalk artwork yesterday on Michigan Avenue, outside the Tribune tower. Tracee is waving and Nancy is wearing the hat. The team chalked from 9:30 am (when the rain ended) until 5:00 pm. It was a long day but the crowds were supportive and excited. And, we were quite proud of the finished product. It has faded significantly due to last night’s storm, however. Oh well, the best art is ephemeral.
