Input: It was in 1865 that two Frenchmen were looking into the future. Edouard de Laboulaye, who studied history, admired the United States greatly. Frederic Auguste Bartholdi was a famous artist. De Laboulaye was thinking about 1876, when the country he respected so much would celebrate its 100th birthday. What gift would be good enough for the people of France to give? Right away, Bartholdi thought of a giant statue. Bartholdi kept thinking about a statue for several years. Then, in 1871, he visited the United States and saw the perfect place for a huge statue. It was Bedloe's Island in New York. The project -- the Statue of Liberty -- got started almost immediately, and Bartholdi went home to France to begin work. However, the statue was not finished in time for the 100th birthday. The United States Congress approved the use of Bedloe's Island on February 22, 1877. During the 100th celebration in 1876, the arm of the statue that would hold the torch was shown in Philadelphia. In 1879 the huge head was put on display in France. For the face of the statue, Bartholdi used his mother as a model. The statue was finally completed in 1884. The work had been difficult enough, but then some really hard work began. The statue had to be taken apart and packed into boxes. It was not until May 1885 that the statue -- in pieces -- left France for its new home. The statue arrived in June. However, the Americans fell behind on their part of the project. They hadn't raised enough money for building the base of the statue. People wondered if the country really needed or wanted such a gift. Finally, though, the money was raised and the base was completed. The last piece of the statue was put in place on October 28, 1886.
Output:
How many years did it take for the Statue of Liberty to be put in place on its base after it was completed?
