Three selections from the Museum's photostream. Francophiles may be interested in browsing more carefully through the several hundred pix of the Paris Exhibition. I don't know whether the color images above are early French autochromes, or whether they were carefully hand-tinted.
And I discover that someone had invented "moving sidewalks" by the turn of the century. More history (and another picture from the Parisian Exposition Universelle at Wikipedia.) You learn something every day.
