1941 Chrysler Royal

The sign facetiously refers to the mannequins as Bonnie and Clyde but Bonnie Parker and Clyde Barrow's criminal careers came to an end in 1934 before this Chrysler was made.
They died in a hail of gunfire in Louisiana while travelling in a 1934 Ford De Luxe V8.
The Saguaro Cactus in the background might also indicate that this is not in Louisiana.
