A space-age tower, left, and a restored giant metal globe called the Unisphere, remain as original structures from the 1964 World's Fair, Tuesday April 1, 2014 in the Queens borough of New York. A group of preservationists is fighting to save the towers and a pavilion of pillars once called the “Tent of Tomorrow,” but others see them as annoying eyesores that should be torn down. Neither option would come cheap: an estimated $14 million for demolition and up to $72 million for renovation. (AP Photo/Bebeto Matthews)
