Bread had to have been cheaper than 9 cents in 1913. I remember buying a loaf of wonder bread for a dime in the 1950s.
Is Wonder bread?
I had doubts about that too, but I looked up "price of a loaf of bread in 1910" and Google said it was 7 cents, which I figured was close enough.
Wasn't the whole point of Wonder Bread that it was made super cheap by injecting air into it instead of making it rise with yeast, or some such thing? The bread in 1913 would have been actual bread, presumably.
