All you have to do is print these out and tape them to your car's bumper! Or, you can put 'em on the back of your bicycle, motorcycle, scooter, or even hang 'em on the wall of your gym locker! :)
Here they are!
I'm not exactly sure when all of these came out, though I KNOW Spider-Man's came out in the '60's, and I SUSPECT all of the DC bumper stickers came out in the '80's, because of the Super Powers sticker. :)
I hope you liked these! I'll be back later with more schtuff, of course! :)
