The stamp bears an artist's rendering of a 1950s-era photo of Parks. It's one of several ways the nation is honoring Parks on Monday.
The Henry Ford museum in Dearborn is hosting a 12-hour celebration. Event-goers are being given the opportunity to take a seat on the Rosa Parks bus inside the museum.
Parks was arrested in 1955 for refusing to give up her seat on a Montgomery, Ala., bus to a white man, an act that helped fuel the civil rights movement.
Parks died in 2005.
