The Official Guide promised "a reproduction of naval submarines under water." The front was among the most striking on the Zone. Neptune and his sea horses reared overhead. Visitors went in and out through the mouths of enormous plaster bullheads, into a grotto vestibule lined with tanks of swimming trout.
The show failed anyway. Some of the Exposition's department heads blamed the name: people did not want to be immersed for fun and seemed afraid they might be. Most were content to admire the front and walk on. It was still unfinished two days before opening.
