I located the picture in the 1955 Delta County Tourist Guide (7th Edition) on page 4. Also on page 4 is the following entry in the What To Do column: "Theatres--Outdoor Drive-In ... B&D Drive-In, Rapid River--individual speakers, refreshments. Hill-Top Drive-In--3/4 mile west of Escanaba on highway 412--individual speakers, confection cafeteria, children's playground, modern rest rooms. Kenmore Drive-In, under construction at the time of printing of this edition, is located on US-2 and 41, four miles north of Escanaba. Opening expected during early summer." The B & D opened in 1949 and closed in the fall of 1956.
