In January 2006, USINT Havana began displaying messages on a scrolling "electronic billboard" in the windows of their top floor. Messages include the George Burns quotation, "How sad that all the people who would know how to run this country are driving taxis or cutting hair."[10] Following a protest march, the Cuban government erected a large number of poles, carrying black flags with single white stars, obscuring the messages. In June 2006, Granma International referred to the billboard as the systematic launching of the crudest insults of our people via the electronic billboard, which, in violation of the most elemental regulations of international law, they think they can maintain with impunity on the facade of that imperial lair.[11] Also during 2006, the Cuban billboards began carrying images of President Bush and Luis Posada Carriles as vampires and axe-murderers.[citation needed] In June 2009, the electronic billboard was turned off, because, according to the United States Department of State, the billboard was not effective in delivering information to the Cuban people.[12] Subsequently, the billboards - including the famous "Señores Imperialistas" sign - are gone as of June 2009.
