Plagued with attendance problems, the 1984 Louisiana World Expo has the distinction of being the only world's fair that has declared bankruptcy during its run. Many blamed the low attendance on the fact that it was staged just two years after Knoxville's 1982 World's Fair just two states away. It also has the distinction of being the last expo held in the United States. Despite its problems, it is fondly remembered by many New Orleans residents and noteworthy architecturally for the groundbreaking post-modern Wonderwall designed by Charles Moore and William Turnball.
