Rochester Tumbler Works, Rochester, Pennsylvania, Postcard Mailed October 1911

In 1900, the Rochester Tumbler Works with its 1200 employees could produce tens of thousands of tumblers and other glass tableware a week. The Pennsylvania factory was part of the National Glass Company, a combination of several independent glass firms created in 1899. Tragically, the glassworks burned in 1901, but a new factory, seen in this postcard, was built.
