During the early years of World War II, women took up most of the milk delivery jobs, as you see in this 1942 photo from the UK.
After the war, however, milk and butter delivery trucks popped up all over the country.
This was a pretty standard scene that many of us remember. They'd even sometimes bring pre-made chocolate milk!
And all of these deliveries can be captured in this great photo from the late 1940's that shows the conversation and community that often happened between deliverymen and their customers.
