The Dream, also known as the Dr. Martin Luther King, Jr.
 Memorial Sculpture, is an outdoor bronze sculpture of Martin Luther King Jr. by Michael Florin Dente, located outside the Oregon Convention Center in Portland, Oregon.
 The 8 ft memorial statue was dedicated on August 28, 1998, the 35th anniversary of King's "I Have a Dream" speech.
 It depicts King plus three allegorical sculptures: a man who symbolizes the American worker, a woman who represents immigration, and a young girl shown releasing King's coattail, who represents, according to Dente, the "letting go" that occurs when people sacrifice their time and energy to engage in a struggle.
 The sculpture is part of the City of Portland and Multnomah County Public Art Collection, courtesy of the Regional Arts & Culture Council.
William Joseph ("Wild Bill") Donovan (January 1, 1883 – February 8, 1959) was an American soldier, lawyer, intelligence officer and diplomat.
 Donovan is best remembered as the wartime head of the Office of Strategic Services (OSS), the precursor to the Central Intelligence Agency, during World War II.
 He is also known as the "Father of American Intelligence" and the "Father of Central Intelligence".
 "The Central Intelligence Agency regards Donovan as its founding father," according to journalist Evan Thomas in a 2011 "Vanity Fair" profile.
 The lobby of CIA headquarters, in Langley, Virginia, now features a statue of Donovan.
 Thomas observed that Donovan's "exploits are utterly improbable but by now well documented in declassified wartime records that portray a brave, noble, headlong, gleeful, sometimes outrageous pursuit of action and skulduggery."

 Lima was selected through a competition that was sponsored by the Brazilian government, which also donated $60,000 for the surrounding plaza and granite base.

 Ceremony attendees included Manhattan Borough President Hulan Jack, Parks Commissioner Robert Moses, Brazilian Ambassador to the United States Joao Calos Muniz, Deputy Assistant Secretary of State of Inter-American Affairs Edward J. Spears, Cardinal Francis Spellman, and Mayor Robert F. Wagner, Jr. Originally located at the northwest corner of Bryant Park, it was moved to its current location along Avenue of the Americas, between 40th and 42nd Streets, in the early 1990s.
 Every September, the Consulate General of Brazil commemorates Andrada and Brazilian Independence Day by hosting a small ceremony at the monument.
