Strap on your goggles and prepare to time travel with Retronaut to the past as you've never seen it. A space suit for dogs. Munchkins enjoying a cigarette break on the set of The Wizard of Oz. Ku Klux Klan members taking a spin on a ferris wheel. These images, and thousands more, make up the captivating world of the Retronaut, the Internet's most popular destination for vintage photography. In the words of Retronaut founder and chief curator, Chris Wild, the past is as exciting as a visit to a foreign country. Here, Wild has selected more than 400 of the best photographs from the site's most visited eras and themes, mashing up Victoriana with vintage advertising from the 60s and 70s with amazing inventions like pants for cows and breast wasershers for women.
