Hansa passenger cars were quite rare. The car on the photo is a Hansa 1100 cabriolet with 1.1 litre, 4 cylinders row engine with 28 HP. The vehicle belonged to a supply unit. An older Henschel lorry can be seen in the background.
This photo of the same vehicle offers a good side view of the beautiful Hansa 1100. In addition, there was a limousine and a cabriolet besides the shown cabriolet-limousine.
