Workers stand at a paper machine in the Oxford Paper Company's Postcard Mill in 1903. That year, the Oxford Paper Company secured what was then considered one of the most valuable contracts in the paper industry--the manufacture of all the postal cards used by the United States Post Office. The Oxford produced the cards at a rate of 3 million per day.

The contract was extended and enlarged for an additional four years on Dec 13, 1905. Numbers 5 and 6 paper machines were installed in 1905 and 1906, respectively, in order to keep up production for the publishing business.
