In 1925, California commemorated the 75th anniversary since it joined the Union with an extravagant party hosted in San Francisco. The event was named the “Diamond Jubilee,” so called due to a “jewel”-encrusted decorative centerpiece and archway in Civic Center Plaza. Festivities began on September 5th, 1925 with an automobile parade followed by water exhibitions of speed boats and seaplanes. Those in attendance could visit the “Joy Zone,” an area dedicated to fun and delights, including games, circus acts, musical performances. The evening concluded at the Civic Auditorium. In the days that followed, there were more motorcades and parades, including a military car show. The final day, September 12th, saw a night-time “electrical light spectacle” parade.
