New stamp honors civil rights icon on 100 birthday

Rosa Parks stamp

The U.S. Postal Service just began offering a new stamp in honor of civil rights icon, Rosa Parks, on what would have been her 100 birthday. 

Parks was arrested in 1955 in Montgomery, Ala., after refusing to give up her seat on a bus. 

She became a rallying point for the civil rights movement. 

Parks died in 2005 as the age of 92.
