Tea, Coffee and Milk Consumption, from Our Private Lives, posted by Michael Stoll on Flickr:
Here duly charted is a major difference in the private lives of Britons and Americans. Cups represent pounds of tea or coffee, and since a pound of tea goes farther, Britons probably drink more tea than Americans do coffee.. As for gallons of milk, Switzerland sets a target for all.
From the book America and Britain: Three Volumes in One, by P Sargant Florence; Lella Secor Florence; K B Smellie. Book published 1946; figures from 1930-1934.
