In 2010, Green created "In Seven Days"... a set of seven silk-screen prints depicting Barack Obama's 2008 presidential election campaign. Green was inspired by her mixed-heritage children to record these events for the future. She gained access to Obama’s campaign, making six trips to events, such as his nomination at the 2008 Democratic National Convention in Denver and Inauguration in Washington D.C. In 2011 a set of "In Seven Days..."was donated to the Library of Congress; another set is in the Metropolitan Museum of Art. This series has also been exhibited at Harvard Law School, Walker Art Gallery and Said Business School.
