This time it is the Big Picture from the Boston Globe to present an exhibit about Russia in Color, with these autochromes from the Prokudin-Gorskii collection at the Library of Congress (USA).
General view of the [Nikolaevskii] cathedral from southwest. Mozhaisk – Prokudin-Gorskiï, Sergeï Mikhaïlovich, 1863-1944, photographer – From Library of Congress
Also I recommend the Big Picture as a regular “reading” for the pictures.
