This is interesting it’s a sign in North Carolina which not only has a picture of the beef it is advertising but also includes the smell. The large sign shows a black pepper and charcoal steak but also includes cartridges with fragranced oil. The aroma is spread with the help of a fan at the bottom of the billboard. The smell is pumped out six hours a day from from 7am to 10am and 4pm to 7pm. Interesting idea but I wouldn’t want to live next door to it.
