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.

Burton Holmes, Extraordinary Traveler. Burton Holmes didn't invent travel stories, slide shows, moving pictures or cross-country lectures, but he put them all together and created the travelogue (a term coined by his manager) as performance art. The site is full of information, pictures and additional links (including companion pages about the Trans-Siberian Railroad) chronicling Holmes' life and legacy.
