LOL... suddenly I want a gallon of fresh whole milk. ;>)
When I was a kid, the milk came in glass bottles shaped somewhat like a bowling pin. Cream on top, with a paper lid with tab on top. My mother would pour the cream into a pitcher and we woukd drink the bluejon. Occasionally we would shake the bottle up, mixing in the cream. After WWII, they started selling homogenized milk and sold it in cartons. and the cream came more often in small bottles/cartons. My only real memory of kindergarten—in the days when the kids were not being prepped for Harvard— was a half-pint of chockolate milk for lunch.
