Hillside Drive-In

This photo appeared in the April 10, 1954 issue of Motion Picture Herald, which should be in the public domain. (Of course, it may have also appeared elsewhere.) The original caption:

The new attraction panel of the Hillside drive-in, Hillside, D., an operation of Sidney Lust Theatres, Washington, D. C., employs large Wagner 17-inch green plastic and 10-inch red plastic letters to form the chanegable copy. Fabricated and erected by the Whiteway Neon Sign Company, New York, the board has two faces with openings 23 feet, 1½ inches long by 85 inches high. Wagner glass and frames were also employed in the installation.
