Transit workers demonstration 1950

A crowd of about 7,000 transit workers mass at the south end of the headquarters of the New York City Board of Transportation at the Holland Tunnel Plaza, April 17, 1950. The demonstrators, mostly maintenance men on the city's subway system, staged the demonstration to dramatize their dispute with the Board of Transportation. The Transport Workers Union (TWU) threatened a strike if even one worker was punished for demonstrating. (AP Photo/John Lindsay)
