Flashback: Looking back at bumper stickers
The back bumper of an automobile provides its owner with personal billboard space.
It's a very public bulletin board for all to read and discover the driver's interests, political opinions and philosophical mantras.
If nothing else is accomplished, at least the car following behind can relieve the boredom of being stuck in traffic by reading the bumper ahead.
Sometimes bumper stickers are laugh-out-loud funny or quirky. Others show an allegiance or affiliation. Still, others are more personal, relating to family, pets or faith.
