There are not many embossed Upjohn glass bottles still in existance. Here are the ones that I am aware of. In the second photo, UP&G are the initials of the Upjohn Pill & Granule Company. The Phenolax bottle is the one embossed Upjohn bottle that is quite common. Phenolax bottles were made in both brown and colorless glass. The earliest Upjohn glass bottles were hand-blown. The first three bottles below are in the collection of Joel Widman.
