The unfinished tower became an eyesore for visitors to the nearby convention center. During its vacancy, people noted that the building appeared to be tilted, similar to the Leaning Tower of Pisa; experts stated that this was an illusion caused when the building was viewed with nearby power poles, which were tilted rather than the building itself. Local residents nicknamed it the "Leaning Tower of Plaza", the "Leaning Tower of Las Vegas", and "Frank's Folly." Moffitt said, "It doesn't tilt. There is only three-eights of an inch difference in diameter from top to bottom." In May 1966, early negotiations were being held with a prospective buyer of the Landmark.
