Bolle Milchwagen

In the 1870s and 1880s, imperial Berlin was growing rapidly, the city expanded and the need for perishable agricultural products such as milk, butter, eggs, meat, vegetables, and fruit could no longer be adequately met by the small, mostly rural trade supplies.
Carl Bolle, a versatile entrepreneur, began, among other things, from 1879 to supply the city with milk and milk products that came from his cows that grazed not far from his tree nursery at Lützowufer 31 and were originally used as fertilizer suppliers. The milk first began to be sold locally in a milk bar, and in the following two years increasingly also via milkmaids who pulled jugs through the city with handcarts.
From around 1881 teams of horses were introduced, each manned by a boy as a coachman (popularly known as Bolle because of the inscription on the wagon) and a milkmaid (Bolle girl) who delivered the milk and had the cash register with her in a tied leather bag. Both were in uniform. Bolle and Bolle girls were a popular part of the cityscape and spread the news and cheeky sayings.

This is one of the models that was made for the "Time Travel Berlin" VR game where you can travel to 20's Berlin streets and "drink" a cup of Bolle milk from the 20th century.
