The Burton Holmes Archive has information about Burton Holmes, the travel writer who became the first person to make filmic travelogues. More importantly, they also have a lot of film clips by Holmes and his associate, André de la Varre, who was also a great travelogue maker himself. Watching these clips is not quite time travel, but it is as close as we can get. Take a look at Reykjavík, Iceland, in 1926, Lake Michigan in 20s, Cairo in 1932 and the 1955 Rio de Janeiro carnival. The later films have sound and narration, but I prefer the silent ones.
