A previously unknown manuscript of a 1941 novel by McKay was authenticated in 2012. Entitled "Amiable With Big Teeth: A Novel of the Love Affair Between the Communists and the Poor Black Sheep of Harlem", the manuscript was discovered in 2009 by Columbia graduate student Jean-Christophe Cloutier in the Samuel Roth Papers, a previously untouched university archive. The novel centers on the ideas and events that animated Harlem on the cusp of World War II, such as Benito Mussolini's invasion of Ethiopia.
