Fa. Welte & Söhne, Freiburg
This old picture shows impressively the size of the Freiburg Welte factory.
In comparision with many other companies like Aeolian, Hupfeld, Loesche, etc, who did a lot of advertising, Welte seems to be much more reserved.
For example, it was easy, to find about 50 ads from Hupfeld within a few month, but it took me years to find only a few ads from Welte.
On the next pages you can have a look at some of the ads, I found.
