Bumper Stickers

If you want to give your message the exposure that it deserves, bumper stickers are one of the best ways to go. They are effective because they are far reaching and mobile. They travel, by default, as far as the vehicles that they are stuck on. They are forever ready to serve their purpose - to deliver the message to anyone who is within seeing distance.
Some bumper stickers can be sneaky and subtle. Some of them can be very obvious and loud, depending on whatever they need to convey. They have been known to cause reactions such as
the honking of horns,
sudden and uncontrollable fits of laughter, or even
impromptu discussions and debates.
