Manitowoc Bottling Works, Wisconsin
This is one of several antique seltzer bottles that I was able to photograph at the 2007 Milwaukee bottle show. This cobalt bottle has vertical ribs or facets and it is wider at the shoulders and hub than in the middle. The contents are etched at "28 oz". The rest of the etching reads, "MANITOWOC BOTTLING / WORKS / MANITOWOC, WIS."
