I definitely DO remember glass milk bottles, and the aluminum (double layered) milk box that was by my back door.
My mother A”H, would put a note rolled up and stuck in the top of one of the empty bottles to tell George, our “milkman” ( I still remember his name!) what she wanted for the next delivery.
I also remember when they had glass bottles in Israel (pre-plastic bags!). The first time I opened a bottle and poured, NOTHING CAME OUT. I didn’t know that the milk in Israel back then was not homogenized, and all the cream came to the top! You had to scoop the cream out of the top of the bottle before you could pour the milk!
