Werrbach L. Milwaukee
This is not a photo of the bottle, but is one that is similar. I still need a photo. The difference is that this one has "MILWAUKEE" stamped below "L. WERRBACH". It is found both with the MILWAUKEE and without. The lettering is very small. I suspect Louis complained to the potter and subsequently went to the very large lettering style. It has the cobalt blob typical of Werrbach clay bottles.
