"Panorama of Paris showing the 'Exposition Universelle' of 1867. Hand-painted magic lantern slide. The 1867 Paris World Fair, like many others of its time, was a product of the Industrial Revolution and sought to showcase the industries of different nations. Magic lantern shows began at the end of the 17th century but only became more widespread in the 19th century with the improvement in lamp sources. The shows could range from simple didactic performances to sophisticated shows using double or triple lanterns to produce moving and dissolving images."
