Details:

Thomas A. Edison autographed stock certificate issued by the Edison Portland Cement Company, documenting Edison as the registered owner of forty shares of common capital stock. The certificate is fully executed on the recto with a period engraved portrait of Edison and bears his bold autograph on the verso, endorsing transfer. Dated August 1899, the certificate was printed by the American Bank Note Company and features ornate late-19th-century security engraving, cancellation punch marks that lightly affect the signature, and original issuance details throughout.

Fine condition.

Thomas A. Edison (1847–1931) was one of the most influential inventors and industrialists in American history, holding over 1,000 patents and founding or co-founding numerous companies that helped shape modern technology and infrastructure. Edison established the Edison Portland Cement Company in 1899 with the aim of revolutionizing cement production through new industrial processes. Although the venture ultimately proved commercially challenging, it remains a fascinating example of Edison’s relentless experimentation beyond electricity and communications.
