This kind of stuff is very underrated. We think we can't do anything, but little things like this help a lot- we remoralize others when they see that others are out there spreading info in the real world, and we at least put info in normies faces who otherwise would never get to see it.

Just think of the act of putting a bumper sticker in a crowded area, say a crowded parking lot or somewhere in a subway- in some places 1000+ people will see that in a week. How much effort does placing a bumper sticker take? 5 seconds?
