Dallas Placards

How many times have we seen someone on television walking down the sidewalk, wearing a sign that says "Eat at Joe's," or something similar? Not in Dallas! Under Ord. Nos. 5304; 10372; and 22061, it is illegal to "to carry or hold by hand or otherwise, any billboard, showcard, placard or advertisement or sign of any description for the purpose of advertising" on streets, sidewalks, or any other public property.
