From John's piece:
"All of us are living in a fragile time for our fundamental rights, at least here in America. It seems our news and social feeds are filled with daily attacks on womens' rights. Revolutionary posters have always been rallying cries, and Lou and I felt like we might have a chance to evoke those here, as well as serve the novel's intentions. When I thought about who Ruby was, I thought of the 1940's image of Rosie the Riveter, as imagined by J. Howard Miller and Norman Rockwell (with genius inspiration from Michelangelo's Sistine Chapel). I thought of the grace of Sandro Botticelli's The Birth of Venus, along with Russian revolution posters, and Howard Chandler Christy's 'Fight or Buy Bonds' painting."
