Answer is "Milkman's cart"

A milkman's cart was a type of vehicle that was once used to deliver milk to households. It typically consisted of a small, two-wheeled cart that was pulled by a horse or sometimes pushed by a human. The cart would be loaded with bottles or other containers of milk, which would be delivered to homes along a designated route.

The milkman's cart was a common sight in many neighborhoods throughout the first half of the 20th century, particularly in urban areas. However, as home refrigeration became more common and supermarkets began to sell milk, the use of milkman's carts for home delivery declined. Today, milk delivery by cart is still practiced in some areas, but it is much less common than it once was.
