Its interesting to see how things had changed at the time this photo was taken in the mid-1930s after Prohibition which began in 1920, ended on December 5, 1933. At this roadside drive-in restaurant, a carhop served Magnolia Beer (note the sign at the far end of the building) that was kept in an attractive art deco cooler to patrons sitting in a Packard roadster. It appears that the picture was taken down south as the brew was produced by the Galveston-Houston Breweries.
Note that the Packard was equipped with an antenna mounted under the running board signifying that it was equipped with a radio. The photo is via the Jazz Era Vehicle Archive Facebook page.
The second photo (below) includes another attractive roadster from the period, a 1930 Model “A” Ford. Note that this police car has no convertible top or it was removed. This was a fairly common practice with open police cars of the era to provide for better visibility above and around the car. The image is via the Vintage Philadelphia Facebook page.
