Two attractive certificates from the company issued in 1879. Both certificates are issued for 2 preferred shares. Large vignette of the Eads Bridge, built over the MIssissippi River to connect St. Louis and East St. Louis, Illinois. At 520 feet between the piers, the center arch of Eads Bridge was the longest rigid span ever built at the time of its construction. Extending more than 100 ft below water level, the foundations for Eads Bridge were the deepest underwater constructions of their time. They were installed using pneumatic caissons, a pioneering application of caisson technology in the United States and, at the time, by far the largest caissons ever built. The Eads Bridge caissons were the model for subsequent projects, including the Brooklyn Bridge, which was constructed just a few years later (wikipedia). Both certificates have punch hole cancels.Date: Country (if not USA): State: MissouriCity: Provenance: Ken Prag Collection
