Starting in 1920, Californians began celebrating Public Schools Week in April. Following World War I, teachers in California were scarce and classrooms were over-crowded, and to drum up support for schools, the Grand Lodge of Masons of California launched the annual observation. Out of that celebration grew Parents’ Day (later Exhibit Day) at the college and high school. The event was suspended during World War II. This small brochure was distributed to parents on Thursday, April 15, 1948, the 31st annual event, as they wandered through various exhibits in the late afternoon and evening. Over 1,500 parents and interested townspeople attended the event, along with seniors from ten surrounding high schools. Guided tours enabled visitors to see each campus department.
