To give the screen structure a more substantial-looking base, Lee designed a series of tall ladder-like structures (6) that he covered with translucent corrugated plastic panels. This structure may have been illuminated from within at night to attract customers.
This view of the screen shows the typical drive-in parking lot and speaker stanchions. The wings flanking the projection screen were built to deflect light from passing cars and also to obstruct the view of the screen from non-paying viewers outside the parking lot.
The Rancho Drive-In in San Diego was built in the same year (1948) as the Edwards Drive-In in Arcadia. Although no construction photos survive, the construction technique was presumably similar. In this example, Lee used the street side of the screen structure to feature a colorful mural-like scene of the Mexican landscape illuminated from behind, a cultural reference appropriate to the border city of San Diego.
