All these were in various spots at the National Museum of American History. These are the seats at the famous Civil Rights sit in in Greensboro NC. Much like the NFL anthem protests today, racist white people hated these protests.

This was a suitcase from a Japanese-American family who were sent to the Internment Camps during World War II.
