Picture C

The picture that is present to the left represents an attractive advertisement because it shows a Filet-O-Fish as a fish bowl in the shape of a burger with a fish inside of it to make it look more appealing. I did find this attractive source effective, because it makes me want to go to McDonalds and get a Filet-O-Fish due to how appealing they made it look in this advertisement. http://graphicdesignjunction.com/2012/01/35-clever-poster-advertisement-ideas/
