The Olympic tracksuit worn by Tommie Smith when he raised a fist in protest. A donation can from America's first gay pride march. The first manned spacecraft to orbit the moon. These are just some of the objects on display at various Smithsonian Institution museums that we have gathered to create "time capsules" of America's most impactful moments. From the transformative year of 1968 to the journey of the LGBTQ movement in America, we explore specific times and events in our nation's history, captured through remarkable artifacts.
