English: Unretouched three-colour collotype of the painter Albert Bierstadt (1830 - 1902), made by his brother Edward Bierstadt (1824 - 1906). This may be the oldest surviving real color photograph of a human being.

At the sitting, three pictures through different color filters were made. The sitter had to stay perfectly still for multiple minutes. Then, the negatives were printed on top of each other with the colour of their respective filter, thus showing a full colour image.

The exact date it was made is unknown, but Bierstadt sent this print to Elbridge T. Gerry on November 11, 1895.

Edward Bierstadt first exhibited colour photographs in 1878 and colour portrait photographs in 1892. In 1895 he claimed to have made colour portraits by July 1890.
