The Edison Portland Cement Company was a venture by Thomas Edison that helped to improve the Portland cement industry. He was notably developing an iron ore milling process when he discovered a market in the sale of waste sand to cement manufacturers. Edison therefore decided to set up his own cement company, founding it in New Village, NJ in 1899, and went on to supply concrete for the construction of Yankee Stadium in 1922.

This item comes with a Certificate from John Reznikoff, a premier authenticator for both major 3rd party authentication services, PSA and JSA (James Spence Authentications), as well as numerous auction houses.
