M. W. W. CO.
Menasha Wooden Ware is now the Menasha Packaging Company. Turn over a brown corrugated box in the United States and it is quite likely that it was produced by a Menasha company. Yet this now large packaging business started make wooden buckets and other wooden items that would have been in demand during the 19th century.
This stamp was cancelled the year before the death of the company's founder, Elisha Smith. At that time the company was a well established brand across the midwest and well known in other parts of the United States.
