[4]: 85 Other artists who later joined the union included Balcomb Greene and his wife Gertrude, Ibram Lassaw, Michael Loew and Mark Rothko.
[3] A magazine, Art Front, was published from November 1934, initially in collaboration with the Artists Committee of Action, which had formed to protest the destruction by Nelson Rockefeller of Diego Rivera's mural Man at the Crossroads earlier that year.
