Did you notice the change? is an exhibition organized by Julia Rodenberger and Zara Hayat. Featuring work by local high school students that explores ideas of transformation and the passage of time, a pop-up version of this exhibition took place last fall at the Haverhill Art Walk, and now has been expanded and revisited with the Essex Art Center galleries in mind. Participatory workshops will provide opportunities for the public to contribute to the exhibition during its run.
