Like many of her contemporaries she was very upset by the death sentence of the Italian immigrants Sacco and Vanzetti; she wrote four poems about them. Some of her co-campaigners were Dorothy Parker, G.B. Shaw, Upton Sinclair and H.G. Wells. This photo was made the day before the execution. According to the caption '[Millay is taken] under arrest with another woman by plain clothesmen and police. Both women were participants in the "Death March" by Sacco-Vanzetti sympathizers in front of the State House, and were among the many picketers arrest today.' Far left we see Millay detained by a plainclothesman, who at his other side holds an elderly woman with a grim face. She is flanked by a uniformed policeman. Behind them walks another policeman detaining two men (one is smiling).
