Ice cream shop menu from February 1938.
The prices look great, but according to this site, in 1938, the average annual salary was $1,700, a house cost $6,400, a gallon of gas was 20 cents, and a loaf of bread was 9 cents, so a milk shake had to be a huge treat.
I also love the flavors: licorice ice cream? And plum pudding? And as near as I can figure, it looks like "Whitehouse" ice cream was vanilla ice cream with chunks of cherries in it.
