As hundreds of thousands of Americans take to the streets to advocate for gun control, many are posting pictures of their favorite signs on social media.

The “March for Our Lives” protests, taking place at 843 events around the world, is already one of the largest political mobilizations in recent history.

Sen. Bob Menendez (D-NJ) noted that “protest signs can become searing images that stick with you for years” and “sometimes they even change minds.”
