House leaders and the head of the U.S. Postal Service unveiled a new stamp Wednesday honoring the late Rep. John Lewis.

The stamp design features a 2013 photograph of the Georgia Democrat taken by Marco Grob for Time magazine, according to a Postal Service news release. The selvage, or a stamp pane's margin, will feature a 1963 photograph taken by Steve Schapiro of Lewis outside a nonviolent protest workshop.
