Albumen stereoview photographs published by Keystone View Company showing Thomas A. Edison in his laboratory and a group portrait identified in the printed title as “A Triumvirate of Friendship; Edison, Ford and Firestone.” Both views appear to date from the early twentieth century and are mounted on standard Keystone gray mounts with printed publisher information along the margins.

The laboratory view is titled “The Most Famous Inventor of the Age, Thomas A. Edison in His Laboratory,” showing Edison seated among electrical and mechanical apparatus. The second stereoview is titled “A Triumvirate of Friendship; Edison, Ford and Firestone,” depicting Thomas A. Edison with Henry Ford and Harvey Firestone standing outside a vine covered structure. Thomas Alva Edison (1847–1931) was one of the most influential American inventors, known for the phonograph, practical electric lighting systems, and numerous industrial innovations.

Printed Keystone text describing Edison’s life and work appears on the reverse of the laboratory stereoview. The mounts carry Keystone View Company imprint lines including Meadville, New York, Portland, Oregon, London, and Sydney. Handwritten dates and pencil notations appear on the versos.
