Morosco didn't take over the Burbank until 1899. I'm going to guess that the grandstand was built for La Fiesta...perhaps for the one coinciding with McKinley's May 1901 visit. Here's an image part of that parade, one with another grandstand. Caption reads: "May 9, 1901: Carriage carrying Pres. William McKinley turns north on Broadway at 6th Street during La Fiesta Parade." Bradford Hulse was at 212 W Sixth....

The bleachers at the NEC of Sixth & Main were later replaced with the Kerckhoff Building...
