The Forman Bottling Co was not listed in the 1892 Yonkers Directory nor were they listed in the Directories from 1902 to 1917. The Directories from 1893 to 1901 could not be found so it’s probable that the business falls within this period.
The only reference I could find is a lawsuit that began in 1903 between Forman Bottling Co and Wittemann Brothers. The suit involved ginger ale labels produced by both companies that so closely resembled each other as to be likely to deceive the public. I can’t even confirm that it’s the same Forman Bottling Co.
The bottle I found is a champagne style (12 oz) with a tooled blob finish so it fits the late 1800’s time frame.
