Motorola: Don't Txt Signs

In Brazil, the "No Parking" sign is a common symbol. In it, we see the letter E ("estacionar" = park), crossed by a red line inside a red circle. For our consciousness campaign, we made identical signs, but using all of the other letters and we put them in the same places that No Parking signs are found. These unusual signs attracted the immediate attention of motorists and pedestrians alike, getting them to stop and read our message: while driving, every letter is prohibited.
