Henk & Co - Milwaukee
Henk also operated out of Waukesha, so this bottle could be from either (or both). This has the identical stamp to the salt glazed one and both are extremely rare. It has an Albany slip decoration inside and out. In the early 1980's I got a small shard of this bottle that was dug in a construction site. In the 1990's I was lucky enough to get a whole example, an then just two weeks later got a salt glazed one from a completely different source.
