At the finals — held at MSLO HQ in Chelsea’s historic Starrett-Lehigh Building — a winning poster was picked from each grade level after being judged by a panel that included the artist behind the original Earth Day poster, Martin Carey (also, coincidentally, the father of Martha Stewart Living food editor Sarah Carey), New York City Parks Commissioner Adrian Benepe, and Stewart herself. All of the finalists' posters, not just the winning five, were on display with many of the very excited artists — along with their parents and teachers — on-hand at the gathering. And since this was a Martha event, there were plenty of delicious nibbles to munch on including deviled eggs sourced from Stewart’s farm and an array of locally produced cheeses and veggies.
