I am pretty sure I will be able to find images about German immigrants in this database. German immigration is part of the German SOLs. In the long run I will probably have a separate list on this topic.
This picture gallery is available for teaching. The pictures were taken in 1998, therefore some images are outdated. However, I found very interesting images from modern Germany. This site is definitely much more than the usual tourist images of old houses.
